net: dsa: felix: suppress -EPROBE_DEFER errors
[ Upstream commit e6934e4048c91502efcb21da92b7ae37cd8fa741 ]
The DSA master might not have been probed yet in which case the probe of
the felix switch fails with -EPROBE_DEFER:
[ 4.435305] mscc_felix 0000:00:00.5: Failed to register DSA switch: -517
It is not an error. Use dev_err_probe() to demote this particular error
to a debug message.
