From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com> Resources should be freed on error conditions. i.e, VNIC and VNIC context created in HW and memory allocated in bnxt_vnic_grp_alloc() should be freed.
Added a new function bnxt_vnic_destroy() to do the cleanup. This lightweight function can be used in flow destroy/flush path to avoid duplicate code as well.
