Donald Sharp f096bae46b zebra: Handle crash when backpointer does not exist 
=================================================================
==3058==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000010 (pc 0x7f5bf3ef7477 bp 0x7ffdfaa20d40 sp 0x7ffdfaa204c8 T0)
==3058==The signal is caused by a READ memory access.

the ipset->backpointer was NULL as that the hash lookup failed to find
anything.  Prevent this crash from happening.
