John Baldwin fed2c48af4 Adjust the fdc worker thread startup to work when APs are started earlier.
- Enable the commented out locking in fd_probe().  The worker thread
  should not be running yet (even after these changes), but better to be
  safe than sorry.
- Defer starting the worker thread until after the child drives have been
  probed.  The worker thread startup is moved into a fdc_start_worker()
  thread that the various front ends call at the end of attach.  As a
  side effect this fixes a few edge cases that weren't shutting down the
  worker thread if attach encountered a late failure.
- When executing the initial reset requested by attach in the worker
  thread, use DELAY() instead of a tsleep() if cold is set.
