[PowerPC64] Fix PR24102, floatdisf2_internal2 broken

I'm applying this as obvious, fixing a typo that crept in when I fixed
my original floatdisf2_internal2 to not munge its input.  I don't know
how it happened, as it doesn't seem a likely logic error to make.
Possibly I was renumbering operands and changed a (const_int 2) by
mistake when changing (match_dup 2) to (match_dup 3).

	PR target/24102
	* config/rs6000/ (floatdisf2_internal2): Correct range
	check for numbers that need no bit twiddle.

Bootstrapped etc. powerpc64-linux.
