[PATCH v2 1/1] spl: fix ext4fs_mount return code handling

[Heiko Thiery]

From: Thomas Schaefer <thomas.schaefer at kontron.com>

- 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.

v1 -> v2:
 - directly return -1 instead of goto end (Tom Rini).
