mac80211: stop plink timer only on mesh interfaces

Browse Source 
Since mesh_plink_quiesce() would unconditionally delete
the plink timer, and the timer initialization was recently
moved into the mesh code path, suspending with a non-mesh
interface now causes a crash. Fix this by only deleting
the plink timer for mesh interfaces.
