[FORTRAN PATCH] Quash two -Wlogical-not-parentheses warnings

[Marek Polacek]

These two issues are the last ones blocking moving -Wlogical-not-parentheses
to -Wall.  I tried to fix them, but my attempts failed, so I opened
PR62270.  I hope we could for now go with the following; it only quiets
the warning, but otherwise does not change the code.  Hopefully someone
familiar with the Fortran codebase will take a look at that PR...

	* interface.c (compare_parameter): Wrap LHS of a comparison in parens.
	* trans-expr.c (gfc_conv_procedure_call): Likewise.
