    arch/risc-v: Fix debugging syscall info
    
    This commit fixes an issue when `CONFIG_DEBUG_SYSCALL_INFO=y`: the
    `cmd` variable doesn't exist (instead, `regs[REG_A0]` represents
    the syscall command directly. Also, it fixes the parameter for
    `up_dump_register`, as `tcb` is a pointer here. By applying these
    fixes, debugging syscall info is now possible again.
