[PATCH 4/5] net/bnxt: fix memory leak in VF VNIC query error path

[Mohammad Shuab Siddique]

From: Kishore Padmanabha <kishore.padmanabha at broadcom.com>

bnxt_hwrm_func_vf_vnic_query_and_config() allocates vnic_ids before
calling bnxt_hwrm_func_vf_vnic_query(), but returns without freeing it
when that call fails.

Free vnic_ids on the error path too.

Fixes: 49947a13ba9e ("net/bnxt: support Tx loopback, set VF MAC and queues drop")
