8350480: RISC-V: Relax assertion about registers in C2_MacroAssembler::minmax_fp

[RealFYang]

Hi, please review this trivial change.
The current assertion about the registers is more than needed.
It requires that dst, src1 and src2 must be different from each other.
But the code only required that dst must be different from src1 and src2.
Patch simply relaxes the assersion removing the unneeded constraint.
fastdebug builds OK with change.
