ice: pass VSI pointer into ice_vc_isvalid_q_id

commit a2160599

 upstream.

The ice_vc_isvalid_q_id() function takes a VSI index and a queue ID. It
looks up the VSI from its index, and then validates that the queue number
is valid for that VSI.

The VSI ID passed is typically a VSI index from the VF. This VSI number is
validated by the PF to ensure that it matches the VSI associated with the
VF already.

In every flow where ice_vc_isvalid_q_id() is called, the PF driver already
has a pointer to the VSI associated with the VF. This pointer is obtained
using ice_get_vf_vsi(), rather than looking up the VSI using the index sent
by the VF.

Since we already know which VSI to operate on, we can modify
ice_vc_isvalid_q_id() to take a VSI pointer instead of a VSI index. Pass
the VSI we found from ice_get_vf_vsi() instead of re-doing the lookup. This
removes some unnecessary computation and scanning of the VSI list.

It also removes the last place where the driver directly used the VSI
number from the VF. This will pave the way for refactoring to communicate
relative VSI numbers to the VF instead of absolute numbers from the PF
space.
