dispatcher: Fix rare crash with 'pvar_algo_pattern' (part 2)
Commit fe1a50d251 was a quick-fix attempt, but the race condition was
still there, and continuing to cause rare crashes during 'ds_reload' if
using the 'pvar_algo_pattern' feature.
Long story short: pv_get_spec_value() on SHM-allocated structs has a
high risk of running into concurrency issues, depending on the spec in
use. Here, the issue happened to be with the $stat(xxx) algo pattern,
where 2 or more SIP workers performed concurrent READ/WRITE on it,
leading to a crash.
Many thanks to Eric Tamme from Five9 for reporting & testing!
