Two small patches for gfortran warnings

[Andreas Jaeger <aj at suse dot de>]

I get these warnings compiling gfortran:
/cvs/gcc/libgfortran/io/transfer.c:442: warning: unused variable ‘i’
/cvs/gcc/libgfortran/intrinsics/unpack_generic.c:194: warning: passing argument 1 of ‘unpack1’ discards qualifiers from pointer target type

The first patch removes the unused variable, the second one removes
the const for the return type.  I've committed them after testing on
Linux/x86-64 as obvious,

	* intrinsics/unpack_generic.c: Remove const from parameter.

	* io/transfer.c (formatted_transfer): Remove unused variable.
