reiserfs: Don't call reiserfs_get_acl() with the reiserfs lock

reiserfs_get_acl is usually not called under the reiserfs lock,
as it doesn't need it. But it happens when it is called by
reiserfs_acl_chmod(), which creates a dependency inversion against
the private xattr inodes mutexes for the given inode.

We need to call it without the reiserfs lock, especially since
it's unnecessary.
