net/bnxt: fix HWRM and FW incompatibility handling

Browse Source 
Fix to return an error when the HWRM version that the driver
is compiled against is incompatible with the FW that is actually
running on the card. This is determined based on the req length
indicated by FW against the value supported in the HWRM.
