ICE on wrong code [PR94192].
The idea is not have another resolution of a pointer if an error has
occurred previously.

PR fortran/94192
* resolve.c (resolve_fl_var_and_proc): Set flag "error" to 1 if
pointer is found to not have an assumed rank or a deferred shape.
* simplify.c (simplify_bound): If an error has been issued for a
given pointer, one should not attempt to find its bounds.

* gfortran.dg/bound_resolve_after_error_1.f90: New test.
