Fix the acpi attachment to always start the worker thread.

The previous change to split the worker thread start out of fdc_attach()
did not start the worker thread if the fdc device in the ACPI namespace
did not have an _FDE method.  This fixes hangs when booting with a
floppy controller enabled on certain machines with ACPI.
