[Qemu-devel] [PATCH v3 12/22] raw-win32: Set request_alignment during .bdrv_refresh_limits()

[Eric Blake <eblake@redhat.com>]

We want to eventually stick request_alignment alongside other
BlockLimits, but first, we must ensure it is populated at the
same time as all other limits, rather than being a special case
that is set only when a block is first opened.

In this case, raw_probe_alignment() already did what we needed,
so just fix its signature and wire it in correctly.
