net/bnxt: fix FW rule deletion on representor create

Truflow stack adds VFR to VF and VF to VFR conduits when VF
representor is created. However, in the ingress direction the
VF's fw rules conflict with Truflow rules, resulting in not hitting
the Truflow VFR rules. To fix this, fw is going to remove it’s
VF rules when vf representor is created in Truflow mode and will
restore the removed rules when vf representor is destroyed.

This patch invokes the vf representor alloc and free hwrm commands
as part of which fw will do the above mentioned actions.
