ipcpd: Refactor create_r and flow_req_arr

The API calls for the IPCP to inform the IRMd of IPCP creation and
incoming flow request had the pid_t in the call. This pid_t is removed
and the getpid() call is now placed inside the function. Also
refactors the cleanup for the main() functions of some of the lower
IPCPs.
