CVE-2025-40239

net: phy: micrel: always set shared->phydev for LAN8814

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

net: phy: micrel: always set shared->phydev for LAN8814

Currently, during the LAN8814 PTP probe shared->phydev is only set if PTP
clock gets actually set, otherwise the function will return before setting
it.

This is an issue as shared->phydev is unconditionally being used when IRQ
is being handled, especially in lan8814_gpio_process_cap and since it was
not set it will cause a NULL pointer exception and crash the kernel.

So, simply always set shared->phydev to avoid the NULL pointer exception.
