perf trace: Fix leaks of 'struct thread' in set_filter_loop_pids()

Browse Source 
[ Upstream commit 30d20fb1f84ad5c92706fe2c6cbb2d4cc293e671 ]

I've found some leaks from 'perf trace -a'.

It seems there are more leaks but this is what I can find for now.

Fixes: 082ab9a18e ("perf trace: Filter out 'sshd' in the tracer ancestry in syswide tracing")
