net: ravb: avoid dereferencing an invalid PTP clock

In the Linux kernel, the following vulnerability has been resolved:

net: ravb: avoid dereferencing an invalid PTP clock

The PTP clock is unavailable before the first open, so querying its
index can dereference a NULL pointer. Registration failures can also
leave an error pointer in priv->ptp.clock.

Cache the PHC index separately and report -1 while no clock is
registered. Normalize registration errors to NULL and preserve the
static timestamping capabilities.
