qed: Correct doorbell configuration for !4Kb pages

Browse source

When configuring the doorbell DPI address, driver aligns the start
address to 4KB [HW-pages] instead of host PAGE_SIZE.
As a result, RoCE applications might receive addresses which are
unaligned to pages [when PAGE_SIZE > 4KB], which is a security risk.
