[PATCH] net: dsa: sja1105: Fix return value check in sja1105_ptp_clock_register()

[YueHaibing]

drivers/net/dsa/sja1105/sja1105_ptp.c:869 sja1105_ptp_clock_register() warn: 
passing zero to 'PTR_ERR'

ptp_clock_register() returns ERR_PTR() and never returns
NULL. The NULL test should be removed.

Fixes: bb77f36ac21d ("net: dsa: sja1105: Add support for the PTP clock")
