vdpa: allow a 32 bit vq alignment
get_vq_align returns u16 now, but that's not enough for systems/devices with 64K pages. All callers assign it to a u32 variable anyway, so let's just change the return value type to u32. Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
