Shiraz Saleem b83e4c1e4c RDMA/irdma: Add missing read barriers 
[ Upstream commit 4984eb51453ff7eddee9e5ce816145be39c0ec5c ]

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.
