hv_netvsc: Fix unwanted rx_table reset
In existing code, the receive indirection table, rx_table, is in
struct rndis_device, which will be reset when changing MTU, ringparam,
etc. User configured receive indirection table values will be lost.
To fix this, move rx_table to struct net_device_context, and check
netif_is_rxfh_configured(), so rx_table will be set to default only
if no user configured value.
Fixes: ff4a44199012 ("netvsc: allow get/set of RSS indirection table")
