Ian Rogers 42fd623b58 perf maps: Get map before returning in maps__find 
Finding a map is done under a lock, returning the map without a
reference count means it can be removed without notice and causing
uses after free. Grab a reference count to the map within the lock
region and return this. Fix up locations that need a map__put
following this.
