[PATCH] sh: Make _syscall6() do the right thing.

There was a rather silly and embarrassing typo in the sh _syscall6().
For the syscall ABI we have the trapa value specified as 0x10 + number
of arguments, this was being set incorrectly in the _syscall6() case
which ended up causing some problems for users.
