- Despite other ext4 filesystem functions, ext4fs_mount returns 0 in case of error. - This leads to u-boot crash in case that an SD card with valid partition table but without ext4 filesystem created in a partition is found on SD card. - Fix this by returning a proper error code of '-1' from spl_load_image_ext function in case of ext4fs_mount error.
