Shiraz Saleem 4984eb5145 RDMA/irdma: Add missing read barriers 
On code inspection, there are many instances in the driver where
CEQE and AEQE fields written to by HW are read without guaranteeing
that the polarity bit has been read and checked first.

Add a read barrier to avoid reordering of loads on the CEQE/AEQE fields
prior to checking the polarity bit.
