ipv6: Remove unused var in inet6_dump_ifinfo()

Reported by Stephen Rothwell:

--------------------
Today's linux-next build (x86_64 allmodconfig) produced this warning:

net/ipv6/addrconf.c: In function 'inet6_dump_ifinfo':
net/ipv6/addrconf.c:3833: warning: unused variable 'err'

Introduced by commit 84d2697d9649339215675551eae28ba04068dea1 ("ipv6:
