Anatoly Burakov edf73dd330 ipc: handle unsupported IPC in action register 
Currently, IPC API will silently ignore unsupported IPC.
Fix the API call and its callers to explicitly handle
unsupported IPC cases.

For primary processes, it is OK to not have IPC because
there may not be any secondary processes in the first place,
and there are valid use cases that disable IPC support, so
all primary process usages are fixed up to ignore IPC
failures.

For secondary processes, IPC will be crucial, so leave all
of the error handling as is.
