RDMA/irdma: Use s/g array in post send only when its valid

Browse Source 
commit 2c8844431d065ae15a6b442f5769b60aeaaa07af upstream.

Send with invalidate verb call can pass in an
uninitialized s/g array with 0 sge's which is
filled into irdma WQE and causes a HW asynchronous
event.

Fix this by using the s/g array in irdma post send
only when its valid.
