[PATCH net 2/5] net: lan969x: fix the use of spin_lock in PTP handler

[Daniel Machon]

We are mixing the use of spin_lock() and spin_lock_irqsave() functions
in the PTP handler of lan969x. Fix this by correctly using the _irqsave
variants.

Fixes: 24fe83541755 ("net: lan969x: add PTP handler function")
