RDMA/srp: Fix NULL deref at srp_destroy_qp()
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: 9294000d6d89 ("IB/srp: Drain the send queue before destroying a QP")
