iio-buffer-utils: Really fix sorting of channels

Browse Source 
As per the documentation of g_ptr_array_sort
"Note that the comparison function for g_ptr_array_sort() doesn't take the
pointers from the array as arguments, it takes pointers to the pointers in
the array"
So the arguments to the function
	compare_channel_index (gconstpointer a, gconstpointer b)
needs to be dereferenced to get pointer to iio_channel_info.

The error was included in the fixup for commit 984803b by
the maintainer.

Closes #99
