IB/core: Avoid a potential OOPs for an unused optional parameter
commit 2ff124d597c2df8696169ce0006fc974c49a4569 upstream.
The ev_file is an optional parameter for CQ creation. If the parameter
is not passed, the ev_file pointer will be NULL. Using that pointer
to set the cq_context will result in an OOPs.
Verify that ev_file is not NULL before using.
