Subject: ixgbe: There is no need to update num_rx_pools in L2 fwd offload
Patch-mainline: v4.16-rc1
Git-commit: ff815fb2cf638e0906764c9e0f66bc93703626f1
References: bsc#1101674 FATE#325150 FATE#325151

The num_rx_pools value is overwritten when we reinitialize the queue
configuration. In reality we shouldn't need to be updating the value since
it is redone every time we call into ixgbe_setup_tc so for now just drop
the spots where we were incrementing or decrementing the value.
