ice: Skip PTP HW writes during PTP reset procedure
Block HW write access for the driver while the device is in reset to
avoid potential race condition and access to the PTP HW in
non-nominal state which could lead to undesired effects
Fixes: 4aad5335969f ("ice: add individual interrupt allocation")
