BACKPORT: net: release reference to inet6_dev pointer

Browse source 
commit 5cb249686e67dbef3ffe53887fa725eefc5a7144 upstream.

addrconf_prefix_rcv returned early without releasing the inet6_dev
pointer when the PIO lifetime is less than accept_ra_min_lft.

Change-Id: Ic633a1ea28c96f712dce8875f24227ce02ab86b0
Fixes: 5027d54a9c30 ("net: change accept_ra_min_rtr_lft to affect all RA lifetimes")
