ANDROID: Avoid taking multiple locks in handle_lmk_event
Conflicting lock events have been reported resulting from
rcu_read_lock, mmap_sem (in get_cmdline) and lmk_event_lock.
This CL avoids the possibility of these conditions by moving
handle_lmk_event outside rcu_read_lock and invoking get_cmdline before
lmk_event_lock is taken.
