Fortran: fix issue with multiple references of a procedure pointer [PR97245]

gcc/fortran/ChangeLog:

	PR fortran/97245
	* match.cc (gfc_match_call): If a procedure pointer has already been
	resolved, do not create a new symbol in a procedure reference of
	the same name shadowing the first one if it is host-associated.

gcc/testsuite/ChangeLog:

	PR fortran/97245
	* gfortran.dg/proc_ptr_53.f90: New test.

(cherry picked from commit 5340f48b7639fcc874f64aac214f9ef9ae43d43e)
