IMPALA-6362: avoid Reservation/MemTracker deadlock
Avoid the circular dependency between ReservationTracker::lock_ and
MemTracker::child_trackers_lock_ by not acquiring
ReservationTracker::lock_ in GetReservation(), where an atomic
operation is sufficient.
Testing:
Added a unit test that reproed the deadlock.
