4bddf0c813 hyperv/timesync: Rework time adjustment policy 
- By default, adjust time upon SYNC request.  It can be disabled
  through hw.hvtimesync.ignore_sync_req.  SYNC request will be
  sent by hypervisor the host is resumed, rebooted, etc.
- By default, adjust time upon SAMPLE request, if there is 100ms
  difference between VM time and hypervisor time.  This can be
  disabled through hw.hvtimesync.sample_drift.

And nuke the unnecessary task, since channel callback is running
in a Hyper-V taskqueue nowadays.

86afc9b625 hyperv/storvsc: Deliver CAM_SEL_TIMEOUT upon SRB status error. 
SRB status is set to 0x20 by the hypervisor, if the specified LUN is
unaccessible, and even worse the INQUIRY response will not be set by
the hypervisor at all under this situation.  Additionally, SRB status
is 0x20 too, for TUR on an unaccessible LUN.

Deliver CAM_SEL_TIMEOUT to CAM upon SRB status errors as suggested by
Scott Long, other values seems improper.

This commit fixes the Hyper-V disk hotplug support.
