Subject: Bluetooth: ISO: Fix iso_sock_getsockopt for BT_DEFER_SETUP
Patch-mainline: v6.0-rc1
Git-commit: 9dfe1727b21927c6dd8d703e3a9618b505eb6224
References: jsc#PED-1407

BT_DEFER_SETUP shall be considered valid for all states except for
BT_CONNECTED as it is also used when initiated a connection rather then
only for BT_BOUND and BT_LISTEN.

Fixes: ccf74f2390d60 ("Bluetooth: Add BTPROTO_ISO socket type")
