mm/mmap_lock: remove dead code for !CONFIG_TRACING configurations
make W=1 generates the following warning in mmap_lock.c for allnoconfig
mm/mmap_lock.c:213:6: warning: no previous prototype for `__mmap_lock_do_trace_start_locking' [-Wmissing-prototypes]

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

mm/mmap_lock.c:226:6: warning: no previous prototype for `__mmap_lock_do_trace_released' [-Wmissing-prototypes]
void __mmap_lock_do_trace_released(struct mm_struct *mm, bool write)
On !CONFIG_TRACING configurations, the code is dead so put it behind an
#ifdef.
