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.
