Currently, a wakelock is acquired before vdev start is sent to firmware
and released after a vdev stop response is received. In some cases, this
can cause a race condition where the device will power collapse before
the association process is complete. Instead, release the wakelock after
either vdev up or vdev down is sent to firmware, ensuring the entire
association process is protected.
