riscv: Fix syscall_get_arguments() and syscall_set_arguments()
RISC-V syscall arguments are located in orig_a0,a1..a5 fields
of struct pt_regs.
Due to an off-by-one bug and a bug in pointer arithmetic
syscall_get_arguments() was reading s3..s7 fields instead of a1..a5.
Likewise, syscall_set_arguments() was writing s3..s7 fields
instead of a1..a5.
