syscall: support syscalls without error return on Linux
Add the rawSyscallNoError wrapper function which is used for Linux syscalls that don't return an error and convert all applicable occurences of RawSyscall to use it instead. Fixes #22924 Change-Id: Iff1eddb54573d459faa01471f10398b3d38528dd Reviewed-on: https://go-review.googlesource.com/84485 Run-TryBot: Tobias Klauser <tobias.klauser@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org>
