syscall: fix stack frame sizes in assembly

Browse Source 
for GOOS in darwin freebsd linux nacl netbsd openbsd plan9 solaris windows
do
        for GOARCH in 386 amd64 amd64p32 arm
        do
                go vet
        done
done

These are all real mistakes being corrected, but none
of them should be able to cause problems today
due to the NOSPLIT on the functions.

However, vet has also identified a few important problems.
I'm sending this CL to get rid of the trivial 'go vet' results
before attacking the real ones.
