btrfs: check for error when looking up inode during dir entry replay

commit 0c3da800cb5d95a9e9aa70f948c1bbb9b2c2822d upstream.

At replay_one_name(), we are treating any error from btrfs_lookup_inode()
as if the inode does not exists. Fix this by checking for an error and
returning it to the caller.
