rdma: fix buggy code that the compiler warns about
Get rid of this warning:
drivers/infiniband/sw/rdmavt/cq.c: In function ‘rvt_cq_exit’:
drivers/infiniband/sw/rdmavt/cq.c:542:2: warning: ‘worker’ may be used uninitialized in this function [-Wmaybe-uninitialized]
kthread_destroy_worker(worker);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
by fixing the function to actually work.
Fixes: 6efaf10f163d ("IB/rdmavt: Avoid queuing work into a destroyed cq kthread worker")
