Subject: ipv6/addrlabel: fix ip6addrlbl_get()

From: Andrey Ryabinin <[email protected]>

[ Upstream commit e459dfeeb64008b2d23bdf600f03b3605dbb8152 ]

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.
