Fortran: Fix "str" to scalar descriptor conversion [PR92482]

	PR fortran/92482
gcc/fortran/ChangeLog:

	* trans-expr.c (gfc_conv_procedure_call): Use TREE_OPERAND not
	build_fold_indirect_ref_loc to undo an ADDR_EXPR.

gcc/testsuite/ChangeLog:

	* gfortran.dg/bind-c-char-descr.f90: Remove xfail; extend a bit.
