[kvm-unit-tests PATCH] riscv: Fix argc

[Andrew Jones]

__argc is 32 bits so even rv64 should load it with lw, not just rv32.
This fixes odd behavior such as getting false when testing argc < 2
even though we know argc should be 1. argc < 2 being false comes from
the register comparison using the full register width and the upper
32 bits being loaded with junk.

Fixes: bd744d465910 ("riscv: Initial port, hello world")
