net/cxgbevf: do not allocate control queues

Control queues can not be allocated for VFs. So, add check to
only allocate control queues for PFs. This fixes adapter crash
when an attempt is made to allocate control queues for VFs.

Fixes: 3a3aaabc ("net/cxgbe: add control queue to communicate filter requests")
