evdev: Do not perform spurious detection when spurious is already enabled

When exiting RELEASE_DELAYED state, do not transition into states to detect
the need for spurious mode (RELEASE_WAITING, MAYBE_SPURIOUS).
RELEASE_DELAYED is only entered when spurious mode is enabled, there is no
need to detect the need for spurious mode again.
