When running device-introspect-test, a memory leak occurred in the
mss_timer_init function, so use ptimer_free() in the finalize function to avoid
it.
ASAN shows memory leak stack:
Indirect leak of 192 byte(s) in 2 object(s) allocated from:
#0 0xffffab97e1f0 in __interceptor_calloc (/lib64/libasan.so.5+0xee1f0)
