nfp: checking parameter process for rx-usecs/tx-usecs is invalid
Use nn->tlv_caps.me_freq_mhz instead of nn->me_freq_mhz to check whether
rx-usecs/tx-usecs is valid.
This is because nn->tlv_caps.me_freq_mhz represents the clock_freq (MHz) of
the flow processing cores (FPC) on the NIC. While nn->me_freq_mhz is not
be set.
Fixes: ce991ab6662a ("nfp: read ME frequency from vNIC ctrl memory")
