RDMA/bnxt_re: Fix driver crash on unaligned PSN entry address
When computing the first psn entry, driver checks for page alignment. If
this address is not page aligned,it attempts to compute the offset in that
page for later use by using ALIGN macro. ALIGN macro does not return
offset bytes but the requested aligned address and hence cannot be used
directly to store as offset. Since driver was using the address itself
instead of offset, it resulted in invalid address when filling the psn
buffer.
Fixed driver to use PAGE_MASK macro to calculate the offset.
