[ 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().
Patch reworked to handle the different pre-split context.
