Subject: [PATCH] net/bnxt: check for invalid vNIC id

[ backported from upstream commit e9950366d08f20e4d968fd76dcd0d5bc8afc09a0 ]

Passing an invalid fw_vnic_id to the firmware will cause the
bnxt_hwrm_vnic_plcmode_cfg command to fail.
Add a check for VNIC id before sending message to firmware.

Fixes: daef48efe5e5 ("net/bnxt: support set MTU")
