Fix some bugs in how ext4_end_enable_verity() and
f2fs_end_enable_verity() handle failure to enable verity on the file.

This is intended to supersede the f2fs patch from Yunlei He
(https://lore.kernel.org/r/20210302113850.17011-1-heyunlei@hihonor.com,
 https://lore.kernel.org/r/20210301141506.6410-1-heyunlei@hihonor.com,
 https://lore.kernel.org/r/c1ce1421-2576-5b48-322c-fa682c7510d7@kernel.org).
I fixed the same bugs in ext4 too, reworked the functions to cleanly
separate the success and error paths, and improved the commit message.

These patches can be taken independently via the ext4 and f2fs trees.
I've just sent them out together since they're similar.

  ext4: fix error handling in ext4_end_enable_verity()
  f2fs: fix error handling in f2fs_end_enable_verity()
