bnxt_free_all_hwrm_rings() was freeing all the Rx Rings including
zero-ing out the memory for the Aggregration rings, but was not issuing
the FW cmd to destroy the AGG ring(s) from HW. This would manifest in
problems when port stop/port start would be issued as there would be a
HW ring leak everytime port stop was issued.
