Davidlohr Bueso 9c21dae291 ipc/shm: properly return EIDRM in shm_lock()
When getting rid of the general ipc_lock(), this was missed furthermore,
making the comment around the ipc object validity check bogus.  Under
EIDRM conditions, callers will in turn not see the error and continue
with the operation.
