parisc: move dereference_function_descriptor to process.c
Commit deac93df26b20cf8438339b5935b5f5643bc30c9 fixed up printing of %pF on parisc, but added the dereference_function_descriptor prototype to module.c... this isn't a particularly wise idea as module.c might not always be compiled. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
