libstdc++: Remove redundant branches in countl_one and countr_one [PR 98226]

There's no need to explicitly check for the maximum value, because the
function we call handles it correctly anyway.

libstdc++-v3/ChangeLog:

	PR libstdc++/98226
	* include/std/bit (__countl_one, __countr_one): Remove redundant
	branches.
