net: phy: micrel: Fix potential null pointer dereference
In lan8814_get_sig_rx() and lan8814_get_sig_tx() ptp_parse_header() may
return NULL as ptp_header due to abnormal packet type or corrupted packet.
Fix this bug by adding ptp_header check.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: ece19502834d ("net: phy: micrel: 1588 support for LAN8814 phy")
