hv_netvsc: Fix the real number of queues of non-vRSS cases

Browse Source 
[ Commit 6450f8f269a9271985e4a8c13920b7e4cf21c0f3 upstream. ]

For older hosts without multi-channel (vRSS) support, and some error
cases, we still need to set the real number of queues to one.
This patch adds this missing setting.
