eina: Set it to NULL before next iteration

it might have been free'd by the user, so set it to NULL before next
iteration. This is an attempt to fix CID 1039913 and 1039914.

We don't use the pointer value, only the pointer, so the error is wrong.
Could flag the error in coverity, but if this fixes it, we wont see the
error in other situations.
