bonding: fix two compiler warnings

	Fix two compiler warnings that are new with recent versions of gcc
(apparently 4.2 and up).  One is fixed by refactoring; this change was
supplied by Stephen Hemminger.  The other was fixed by labelling the
variable as uninitialized_var() after confirming via inspection that it
cannot actually be used uninitialized.
