perf test: Fix a memory leak in thread_map_remove test
The str should be freed after creating a thread map. Also change the open-coded thread map deletion to a call to perf_thread_map__put(). $ perf test -v 44 44: Remove thread map : --- start --- test child forked, pid 165536 2 threads: 165535, 165536 1 thread: 165536 0 thread: ================================================================= ==165536==ERROR: LeakSanitizer: detected memory leaks Direct leak of 14 byte(s) in 1 object(s) allocated from: #0 0x7f54453ffe8f in __interceptor_malloc ../../../../src/libsanitizer/asan/asan_malloc_linux.cpp:145 #1 0x7f5444f8c6a7 in __vasprintf_internal libio/vasprintf.c:71 SUMMARY: AddressSanitizer: 14 byte(s) leaked in 1 allocation(s). test child finished with 1 ---- end ---- Remove thread map: FAILED!
