btrfs: use inode already stored in local variable at btrfs_rmdir()

[ Upstream commit 9f82a4ed34d870b5719f9b95f7da4f74d3325a6f ]

There's no need to call d_inode(dentry) when calling btrfs_unlink_inode()
since we have already stored that in a local inode variable. So just use
the local variable to make the code less verbose.
