Merge branch 'hv_netvsc-Add-init-of-send-table-and-var-renames'

Haiyang Zhang says:

====================
hv_netvsc: Add init of send table and var renames

Add initialization of send indirection table. Otherwise it may contain
old info of previous device with different number of channels.

Also, did some variable renaming for easier reading.
