net: dsa: felix: initialize "err" to 0 in felix_check_xtr_pkt()
Automated tools complain that felix_check_xtr_pkt() has logic to drain
the CPU queue on the reception of a PTP packet over Ethernet, yet it
returns an uninitialized error code in the case where the CPU queue was
empty.
This is not likely to happen (/possible if hardware works correctly),
but it isn't a fatal condition either. The PTP packet will be dequeued
from the CPU queue when the next PTP packet arrives. So initialize "err"
to 0 for the case where nothing was dequeued during this iteration.
