Anatolij Gustschin b4fc6f2214 video: cfb_console: fix hang if splashimage file is missing 
If the splash file doesn't exist, the booting stops bricking
the boards. Check return value of prepare function and stop
decoding the logo data if splash prepare stage failed.

/*
* cfb_console.c
*
* Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
*
* At the moment only the 8x16 font is tested and the font fore- and
* background color is limited to black/white/gray colors. The Linux
* logo can be placed in the upper left corner and additional board
* information strings (that normally goes to serial port) can be drawn.
*
* The console driver can use a keyboard interface for character input
* but this is deprecated. Only rk51 uses it.
*
* Character output goes to a memory-mapped video
* framebuffer with little or big-endian organisation.
* With environment setting 'console=serial' the console i/o can be
* forced to serial port.
*
* The driver uses graphic specific defines/parameters/functions:
*
* (for SMI LynxE graphic chip)
*
* VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian
* VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill
* VIDEO_HW_BITBLT - graphic driver supports hardware bit blt
*
* Console Parameters are set by graphic drivers global struct:
*
* VIDEO_VISIBLE_COLS - x resolution
* VIDEO_VISIBLE_ROWS - y resolution
* VIDEO_PIXEL_SIZE - storage size in byte per pixel
* VIDEO_DATA_FORMAT - graphical data format GDF
* VIDEO_FB_ADRS - start of video memory
*
* VIDEO_KBD_INIT_FCT - init function for keyboard
* VIDEO_TSTC_FCT - keyboard_tstc function
* VIDEO_GETC_FCT - keyboard_getc function
*
* CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner.
* Use CONFIG_SPLASH_SCREEN_ALIGN with
* environment variable "splashpos" to place
* the logo on other position. In this case
* no CONSOLE_EXTRA_INFO is possible.
* CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo
* CONFIG_CONSOLE_EXTRA_INFO - display additional board information
* strings that normaly goes to serial
* port. This define requires a board
* specific function:
* video_drawstring (VIDEO_INFO_X,
* VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
* info);
* that fills a info buffer at i=row.
* s.a: board/eltec/bab7xx.
*
* CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last
* character. No blinking is provided.
* Uses the macros CURSOR_SET and
* CURSOR_OFF.
