bnxt_en: Add support to call FW to update a VNIC

Browse source 
Add the function bnxt_hwrm_vnic_update() to call FW to update
a VNIC.  This call can be used when disabling and enabling a
receive ring within a VNIC.  The mru which is the maximum receive
size of packets received by the VNIC can be updated.
