Anand Jain 7b020665d4 btrfs: free btrfs_path before copying inodes to userspace
[ Upstream commit 418ffb9e3cf6c4e2574d3a732b724916684bd133 ]

btrfs_ioctl_logical_to_ino() frees the search path after the userspace
copy from the temp buffer @inodes. Which potentially can lead to a lock
splat.

Fix this by freeing the path before we copy @inodes to userspace.
