Subject: [PATCH net] bnxt_en: fix free-runnig PHC mode 

The patch in fixes changed the way real-time mode is chosen for PHC on
the NIC. Apparently there is one more use case of the check outside of
ptp part of the driver which was not converted to the new macro and is
making a lot of noise in free-running mode.

Fixes: 131db4991622 ("bnxt_en: reset PHC frequency in free-running mode")
