RDMA/srp: Fix NULL deref at srp_destroy_qp()

commit 95c2ef50 upstream.

If srp_init_qp() fails at srp_create_ch_ib() then ch->send_cq
may be NULL.
Calling directly to ib_destroy_qp() is sufficient because
no work requests were posted on the created qp.

Fixes: 9294000d ("IB/srp: Drain the send queue before destroying a QP")
