Ajit Khaparde ed0ae3502f net/bnxt: update ring group after ring stop start 
A Rx ring stop start sequence may result in the FW returning
a different set of Rx ring and AGG ring IDs. If the ring group
is not updated with the new IDs, the HW sees the host driver using
incorrect BD types for the Rx ring and AGG ring. This can cause
the chip to go into a bad state or encounter RE_flush issue
or leak mbufs in the HW.

Fix this by issuing a bnxt_hwrm_ring_grp_free() and an
bnxt_hwrm_ring_grp_alloc() to refresh the ring group information.
