net/idpf: fix checks in multi-queue config and stop

Browse Source 
There's core dump when launching l3fwd with 1 queue 1 core. It's
because NULL pointer is used if fail to configure device.
This patch removes incorrect check during device configuration,
and checks NULL pointer when executing VIRTCHNL2_OP_DEALLOC_VECTORS.

Fixes: 549343c25d ("net/idpf: support device initialization")
Fixes: 70675bcc3a ("net/idpf: support RSS")
Fixes: 37291a68fd ("net/idpf: support write back based on ITR expire")
