RDMA/mana_ib: Drain send wrs of GSI QP

Browse source 
Drain send WRs of the GSI QP on device removal.

In rare servicing scenarios, the hardware may delete the
state of the GSI QP, preventing it from generating CQEs
for pending send WRs. Since WRs submitted to the GSI QP
hold CM resources, the device cannot be removed until
those WRs are completed. This patch marks all pending
send WRs as failed, allowing the GSI QP to release the CM
resources and enabling safe device removal.
