libstdc++: Fix mistake in PR98374 change [PR98377]

The #ifdef RADIXCHAR directive should be moved one line up so that it
also guards the outer if statement, or else when RADIXCHAR is not
defined the outer if statement will end up nonsensically guarding the
declaration of output_length_upper_bound a few lines below it.

libstdc++-v3/ChangeLog:

	PR libstdc++/98377
	* src/c++17/floating_to_chars.cc (__floating_to_chars_precision):
	Fix mistake.
