wl12xx: cancel delayed elp work and clear flags when stopping PLT

Browse Source 
In some cases a race condition can happen if we don't cancel any
pending ELP work before stopping PLT.  With this commit we cancel ELP
work and clear the wl->flags bitmask.  Also clean up the wl elements
after powering off.
