ALSA: hda: Make hdac_device.registered a plain bool
The registered field of hdac_device is a bitfield sharing the same
word with other bitfields like lazy_cache, and those are updated in a
non-atomic read-modify-write manner without any lock. Meanwhile, the
registered flag is read from the unsolicited event worker
concurrently, so the concurrent updates of the neighboring bitfields
may race with it.
Convert it to a plain bool for avoiding such a subtle race. Also
replace the assignments of 0/1 with false/true accordingly.
