hv_storvsc: Account for in-transit packets in the RESET path

Bug Description

Properly account for I/O in transit before returning from the RESET call.
In the absense of this patch we could have a situation where the host may respond to a command that was issued prior to the issuance of the RESET command at some arbitrary time after responding to the RESET command.
Currently, the host does not do anything with the RESET command and so it is ok to wait for the in-transit I/O to be accounted for. If the host side sematics changes, we will have to revisit this.

I have pulled this patch into the precise kernel for testing. If you can test the kernels below and confirm the fix your issue:
