Change Details

The number of segments should be limited to the value reported by the hypervisor, not that value plus VTSCSI_MIN_SEGMENTS (2). We hit this at Isilon because we have increased MAXPHYS.

The `seg_max` value reported to the guest should be two less than the host's maximum, in order to leave room for the request and the response. We hit the "too many segments to enqueue" assertion on OneFS because we increased MAXPHYS to 256 KiB.
