This effectively reverts commit b8d35192
by reverts acpi_os_queue_for_execution() to what it was before that,
except it changes the name to acpi_os_execute() to match ACPICA
20060512.

[ The thread execution doesn't actually solve the bug it set out to
  solve (see

	http://bugzilla.kernel.org/show_bug.cgi?id=5534



  for more details) because the new events can get caught behind the AML
  semaphore or other serialization.  And when that happens, the notify
  threads keep on piling up until the system dies. ]
