sh: remove nargs from __SYSCALL
The __SYSCALL macro's arguments are system call number, system call entry name and number of arguments for the system call. Argument- nargs in __SYSCALL(nr, entry, nargs) is neither calculated nor used anywhere. So it would be better to keep the implementation as __SYSCALL(nr, entry). This unifies the implementation with some other architectures too.
