uml: tidy process.c
Clean up arch/um/kernel/process.c: - lots of return(x); -> return x; conversions - a number of the small functions are either unused, in which case they are gone, along any declarations in a header, or could be made static. - current_pid is ifdefed on CONFIG_MODE_TT and its declaration is ifdefed on both CONFIG_MODE_TT and UML_CONFIG_MODE_TT because we don't know whether it's being used in a userspace or kernel file.
