Subject: [PATCH -next] apparmor: cleanup unused functions in file.h

After changes in commit 33bf60cabcc7 ("LSM: Infrastructure management of
the file security"), aa_alloc_file_ctx() and aa_free_file_ctx() are no
longer used, so remove them, and also remove aa_get_file_label() because
it seems that it's never been used before.
