[PATCH v3 10/16] block/nvme: Replace qemu_try_blockalign(bs) by qemu_try_memalign(pg_sz)

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

qemu_try_blockalign() is a generic API that call back to the
block driver to return its page alignment. As we call from
within the very same driver, we already know to page alignment
stored in our state. Remove indirections and use the value from
BDRVNVMeState.
This change is required to later remove the BlockDriverState
argument, to make nvme_init_queue() per hardware, and not per
block driver.
