perf tools: Fix resource leak of closedir() on the error paths

Both build_mem_topology() and rm_rf_depth_pat() have resource leaks of
closedir() on the error paths.

Fix this by calling closedir() before function returns.

Fixes: e2091cedd51b ("perf tools: Add MEM_TOPOLOGY feature to perf data file")
Fixes: cdb6b0235f17 ("perf tools: Add pattern name checking to rm_rf")
