Subject: [PATCH] 6lowpan: set peer_addr correctly again

A bugfix accidentally changed one line to return the peer_addr
from setup_header, causing it to become unused:

net/bluetooth/6lowpan.c: In function 'setup_header':
net/bluetooth/6lowpan.c:402:14: error: parameter 'peer_addr' set but not used [-Werror=unused-but-set-parameter]

The only user of the variable is a subsequent printk(), and
it is not otherwise initialized, so reverting the changed line
looks like the right fix.

Fixes: fb6f2f606ce8 ("6lowpan: Fix IID format for Bluetooth")
