9ed8110c9b RDMA/irdma: optimize rx path by removing unnecessary copy 
In the function irdma_post_recv, the function irdma_copy_sg_list is
not needed since the struct irdma_sge and ib_sge have the similar
member variables. The struct irdma_sge can be replaced with the
struct ib_sge totally.

This can increase the rx performance of irdma.

The function irdma_uk_cq_init always returns 0, so make it void and delete
all the return value checks.

e93c7d8e8c RDMA/irdma: Process extended CQ entries correctly 
The valid bit for extended CQE's written by HW is retrieved from the
incorrect quad-word. This leads to missed completions for any UD traffic
particularly after a wrap-around.

Get the valid bit for extended CQE's from the correct quad-word in the
descriptor.
