From: Chih-Kang Chang <gary.chang@xxxxxxxxxxx>
When SER L1 triggered, driver need to stop Rx and clear RTW89_FLAG_RUNNING
flag. If track_work check RTW89_FLAG_RUNNING simultaneously, it will check
failed and never queue track_work again, and LPS won't enter either.
Therefore, we cancel delayed work when enter SER L1, and queue delayed work
when leave SER L1.
