[PATCH] RISC-V: Fix the sge<u> ..., x0, ... pattern

[Palmer Dabbelt]

There's no operand 2 here, so referencing it doesn't make sense.  I
couldn't find a way to trigger bad assembly output so I don't have a
test.

gcc/ChangeLog

	PR target/106543
	* config/riscv/riscv.md (sge<u>_<X:mode><GPR:mode>): Remove
	reference to non-existent operand.
---
No new failures on the Linux multilibs on trunk.

LGTM, that's apparently some kind of copy & paste error (from *slt<u>
pattern) when we add this pattern.
