Fix PR fortran/17237: bug in f-valprint.c

This commit fixes the PR mentioned in $subject.  It is about a set but
unused variable that refers to the output format of integer values
printed in Fortran.

This was probably a thinko (like most set-but-unused-vars), but it
could cause an internal error depending on the scenario.  I am sending
a testcase which triggers this error as well.
