[PATCH] flex-array: fix location for nesting of flexible members

[Luc Van Oostenryck]

The warning about the nesting of flexible array members is
given with the location of the outer struct or union but
that is not very interesting. What is needed is the location
of the member causing this nesting.

So, fix the warning message to use the member's location.
