rpc : build_prog_details should iterate program list inside critical
section
While I was analyzing a glusterd crash from free_prog_details, a code
walkthrough detects that we iterate over the rpc svc program list without
been
inside the criticial section. This opens up a possibility of a crash when
there
is a concurrent writer updating the same list. Solution is to read the list
inside lock.
