LSM: fix return value check in safesetid_init_securityfs()
In case of error, the function securityfs_create_dir() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().
Fixes: aeca4e2ca65c ("LSM: add SafeSetID module that gates setid calls")
