Josef Bacik 8a589c56b0 btrfs: don't rewrite ret from inode_permission 
[ Upstream commit 0185c2292c ]

In our user safe ino resolve ioctl we'll just turn any ret into -EACCES
from inode_permission().  This is redundant, and could potentially be
wrong if we had an ENOMEM in the security layer or some such other
error, so simply return the actual return value.

Note: The patch was taken from v5 of fscrypt patchset
(https://lore.kernel.org/linux-btrfs/cover.1706116485.git.josef@toxicpanda.com/)
which was handled over time by various people: Omar Sandoval, Sweet Tea
Dorminy, Josef Bacik.

Fixes: 23d0b79dfa ("btrfs: Add unprivileged version of ino_lookup ioctl")
