video: Fix line padding calculation for 16 and 24 BPP bitmaps
Each row in the pixel array in the bitmap file is padded if necessary so the row size is always a multiple of 4 bytes. In current code the complement of row size to a multiple of 4 bytes is further unnecessarily multiplied by the pixel size. This results in incorrect displaying of bitmaps having row size that is not a multiple of 4 bytes. Fix this by removing the unnecessary multiplication. Tested with 24BPP bitmap and XRGB32 display.
