[PATCH] ufs: remove incorrect unlock_kernel from failure path in ufs_symlink()

ufs_symlink, in one of its error paths, calls unlock_kernel without ever
having called lock_kernel(); fix this by creating and jumping to a new
label out_notlocked rather than the out label used after calling
lock_kernel().
