lsm: add new securityfs delete function

When deleting a directory in the security file system, the existing
securityfs_remove requires the directory to be empty, otherwise
it will do nothing. This leads to a potential risk that the security
file system might be in an unclean state when the intended deletion
did not happen.

This commit introduces a new function securityfs_recursive_remove
to recursively delete a directory without leaving an unclean state.
