ANDROID: GKI: fix up build break where timer_delete_sync() was used

We reverted the commit that renamed del_timer_sync() to
timer_delete_sync() a long while back, but that breaks the build when
new users of the call get merged into LTS releases.  Fix the tc358743
driver by using the "old" name of the function.
