Configuring tx_maxrate via sysfs interface
/sys/class/net/eth0/queues/tx-1/tx_maxrate was not working when
TCs are configured because always main VSI was being used. Fix by
using correct VSI in ice_set_tx_maxrate when TCs are configured.
Fixes: 1ddef455f4 ("ice: Add NDO callback to set the maximum per-queue bitrate")
