perf tools: Fix resource leak of closedir() on the error paths
[ Upstream commit 6080728ff8e9c9116e52e6f840152356ac2fea56 ]
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")
