Andrey Ryabinin 5a7fbabb10 ipv6/addrlabel: fix ip6addrlbl_get() 
commit e459dfeeb6 upstream.

ip6addrlbl_get() has never worked. If ip6addrlbl_hold() succeeded,
ip6addrlbl_get() will exit with '-ESRCH'. If ip6addrlbl_hold() failed,
ip6addrlbl_get() will use about to be free ip6addrlbl_entry pointer.

Fix this by inverting ip6addrlbl_hold() check.

Fixes: 2a8cc6c890 ("[IPV6] ADDRCONF: Support RFC3484 configurable address selection policy table.")
