debug nmea should not sent to upper layer

Debug nmea is a way HAL gets GNSS engine debug information from modem.
It is provided to developers in the for bugreoprt.  Those NMEAs should
be discarded once information is extracted out.  But by mistake, they
are sent to GnssLocationProvider.  They will be in the unknown format
to apps, and they may get truncated too.

Dhanged the condition so these debug nmeas get discarded before they
can possibly passed on to GnssLocaitonProvider.
