[PATCH 06/17] block/nvme: Replace qemu_try_blockalign(bs) by qemu_try_memalign(pg_sz)

[Philippe Mathieu-Daudé]

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.
