[PATCH v2 3/8] net/ice: fix DCF queue config buffer leak

[Anurag Mandal]

ice_dcf_configure_queues() returns -EINVAL without
freeing the virtchnl message it allocated when the
required Rx descriptor ID (RXDID) is not supported,
so the message leaks on each failed port start.

Free it before return.

Fixes: 4b0d391f0eab ("net/ice: add queue config in DCF")
Fixes: f3fddc93de16 ("net/ice: fix build with 16-byte Rx descriptor in DCF")
Cc: stable at dpdk.org
