[Patch, Fortran, OOP] PR 43696: Bogus error: Passed-object dummy argument must not be POINTER

[Janus Weil]

Hi all,

here is my fix for PR 43696. The original test case is fixed by the
two-liner in symbol.c (I'm sure we already had this in the early OOP
implementation, but apparently it got lost at some point, though I
don't remember why).
The parts in resolve.c are needed to fix the ICE in comment #4: The
first hunk prevents the ICE and the other two give the correct error
message.

The patch was regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
