1) Put a watchdog on the NFC Service disable path.
All the bug-reports show we were stuck in _disable(), watch-dog
this path (10 seconds).

2) Only attempt a SE reset once, even if it fails the first time.
All the bugs reports should the _disable() was due to SE reset
on first boot.

3) Grab the NFC service lock before the wake-lock.
So even if someone has NFC service lock, at least we don't
hold a wake-lock waiting for it.
