hyperv/storvsc: Fix busdma constraints
- The BUS_DMA_KEEP_PG_OFFSET flag is needed, since
storvsc_xferbuf_prepare() assumes that only the first segment may have
a non-zero offset, and that all following segments are page-sized and
-aligned.
- storvsc_xferbuf_prepare() handles 64-bit bus addresses, so avoid
unneeded bouncing on i386.
