- 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.

Looking over the code, we should return -1 directly here, goto end isn't going to provide more useful information as we don't have a "real" error code to tell the user. With that change please add:
