Change this to type int as ieee802154_hdr_peek_addrs() can return negative
integers, this is found by static analysis with smatch.

This patch has been applied to the wpan tree and will be
part of the next pull request to net. Thanks!
I took the liberty and changed the fixes tag to the change that
introduced the resaon for the mismatch recently. As suggested by Simon.
