target/qla2xxx: Make demo_mode_login_only modifiable

Browse Source 
Changing this attribute to 0 will mean that all initiators that login
to the target while the target has generate_node_acls=1 will see all
TPG LUNs, which may be the desired behavior in some cases.

(nab: Apply patch without macro changes)
