[PATCH, Fortran, v1] Clarify error message of co_reduce

[Andre Vehreschild <vehre at gmx dot de>]

Hi all,

as noted on IRC is one of the error message in check.c co_reduce misleading.
The attached patch fixes this. The intention of the error message is to tell
that the type of the argument bound to parameter A is of wrong type and not
that an unspecific argument has a wrong type.

If no one objects within 24 h I am planning to commit this patch as obvious to
trunk gcc-7. Bootstrapped and regtested on x86_64-linux-gnu/f25.

Regards,
	Andre
