signal: make force_sigsegv() void
Patch series "signal: refactor some functions", v3.
This series refactors a bunch of functions in signal.c to simplify parts
of the code.
The greatest single change is declaring the static do_sigpending() helper
as void which makes it possible to remove a bunch of unnecessary checks in
the syscalls later on.
This patch (of 17):
force_sigsegv() returned 0 unconditionally so it doesn't make sense to have
it return at all. In addition, there are no callers that check
force_sigsegv()'s return value.
