thunderbolt: Mask ring interrupt on Intel hardware as well

commit 9f9666e653 upstream.

When resuming from system sleep states the driver issues following
warning on Intel hardware:

  thunderbolt 0000:07:00.0: interrupt for TX ring 0 is already enabled

The reason for this is that the commit in question did not mask the ring
interrupt on Intel hardware leaving the interrupt active. Fix this by
masking it also in Intel hardware.
