Andrea Parri (Microsoft) 8eb3e56fd1 hv_netvsc: Reset the RSC count if NVSP_STAT_FAIL in netvsc_receive() 
[ Upstream commit 12bc8dfb83b5292fe387b795210018b7632ee08b ]

Commit 4414418595 ("hv_netvsc: Add validation for untrusted Hyper-V
values") added validation to rndis_filter_receive_data() (and
rndis_filter_receive()) which introduced NVSP_STAT_FAIL-scenarios where
the count is not updated/reset.  Fix this omission, and prevent similar
scenarios from occurring in the future.
