perf tools: Do not remove addr_location.thread in thread__find_map()

The thread__find_map() is to find a map for a given address in the
given thread's address space.  It searches maps based on the cpu mode
and fills various information in the addr_location data structure.

It might change al->maps and al->map, but not al->thread.  Then I
think no reason to not set the al->thread at the beginning.

Also get rid of the duplicate 'al->map = NULL' part.
