RDMA/cxgb4: Add a sanity check in process_work()
The story is that Smatch marks skb->data as untrusted so it generates
a warning message here:
drivers/infiniband/hw/cxgb4/cm.c:4100 process_work()
error: buffer overflow 'work_handlers' 241 <= 255
In other places which handle this such as t4_uld_rx_handler() there is
some checking to make sure that the function pointer is not NULL. I
have added bounds checking and a check for NULL here as well.
