RDMA/ionic: Fix memory leak of admin q_wr

The admin queue work request buffer, aq->q_wr, is allocated via kcalloc in
__ionic_create_rdma_adminq. However, it was not being freed in the
corresponding teardown function __ionic_destroy_rdma_adminq. This results
in a memory leak. Fix this leak by adding the missing kfree(aq->q_wr) in
the destruction path.
