Modified Files:
        src/sys/dev/pci: vioscsi.c

Log Message:
fix number of maximum segments in the queue allocation so that
MAXPHYS-sized tranfer fits inside the indirect descriptor; avoids the
!indirect path in virtio_enqueue_reserve() for these transfers,
which runs out of the vq_entries and triggers XS_RESOURCE_SHORTAGE for
bigger number of outstanding tranfers
