Revert "um: Use swap() to make code cleaner"

commit dddfa05eb5 upstream.

This reverts commit 9b0da3f223.

The sigio.c is clearly user space code which is handled by
arch/um/scripts/Makefile.rules (see USER_OBJS rule).

The above mentioned commit simply broke this agreement,
we may not use Linux kernel internal headers in them without
thorough thinking.

Hence, revert the wrong commit.
