Bluetooth: L2CAP: uninitialized variables in l2cap_sock_setsockopt()

[ Upstream commit 2b70d4f9b20635ac328836e50d183632e1930f94 ]

The "opt" variable is a u32, but on some paths only the top bytes
were initialized and the others contained random stack data.

Fixes: a7b75c5a8c41 ("net: pass a sockptr_t into ->setsockopt")
