asm command: fix default arch 

Before this commit, running `asm mov rax, 0xdeadbeef` would not work on amd64 targets because the default arch was set in the argparse default argument value and it was populated once.

Now, this `default=...` kwarg is not set and instead we fetch current arch inside the `asm` command directly when the user did not pass any architecture value.
