RDMA: Restore ability to fail on SRQ destroy
In similar way to other IB objects, restore the ability to return error on
SRQ destroy. Strictly speaking, this change is not necessary, and provided
here to ensure a symmetrical interface like other destroy functions.
Fixes: 68e326dea1db ("RDMA: Handle SRQ allocations by IB/core")
