This patch converts the IPC RCU header's reference counter to atomic_t. The return of
ipc_rcu_getref() is modified to inform the callers if it actually succeeded.
Now all callers return -EIDRM upon failure and abort the current operation. Two exceptions are
in semaphore code where sem_getref_and_unlock() and sem_getref() trigger a warning but proceed
to freeing up any held locks.
