65fe5a4627 hyperv/hn: Suspend and resume the backend properly upon MTU change. 
Suspend:
- Prevent the backend from being touched on TX path.
- Clear the RNDIS RX filter, and wait for RX to drain.
- Make sure that NVS see the chimney sending buffer and RXBUF
  disconnection, before unlink these buffers from the channel.

Resume:
- Reconfigure the RNDIS filter.
- Allow TX path to work on the backend.
- Kick start the TX eof task, in case the OACTIVE is set.

This fixes various panics, when the interface has traffic and MTU
is being changed.

And nuke the unnecessary task, since channel callback is running

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.
