RDMA/irdma: Fix support for 64k pages

[ Upstream commit 03769f72d66edab82484449ed594cb6b00ae0223 ]

Virtual QP and CQ require a 4K HW page size but the driver passes
PAGE_SIZE to ib_umem_find_best_pgsz() instead.

Fix this by using the appropriate 4k value in the bitmap passed to
ib_umem_find_best_pgsz().
