[PATCH 7/9] staging: hv: fix counting of available buffer slots when send fails

[Haiyang Zhang]

Because the number of available buffer slots doesn't decrease for failed
sends, we should not call netvsc_xmit_completion(), which increase the
count of available slots. In this failed case, just free the memory is
enough.
