[PATCH] Allow BT_SECURITY for L2CAP raw sockets

Hi Marcel,

Here's the patch to permit BT_SECURITY for L2CAP raw sockets. It allows
our BtIO code to be simpler since there's no need to do special L2CAP_LM
tricks when doing paring using L2CAP raw sockets. It seemed to work fine
in my tests (both SSP and legacy pairing) so if it's ok with you I'll
also push the corresponding patch for bluetoothd (which without this
patch would cause EINVAL when trying pairing on a newer kernel).

Johan

Subject: [PATCH] Bluetooth: Permit BT_SECURITY also for L2CAP raw sockets

Userspace pairing code can be simplified if it doesn't have to fall back
to using L2CAP_LM in the case of L2CAP raw sockets. This patch allows
the BT_SECURITY socket option to be used for all types of L2CAP sockets.
