[PATCH 3/5] Bluetooth: Remove *_bh locks from SCO

["Gustavo F. Padovan" <padovan@profusion.mobi>]

From: "Gustavo F. Padovan" <padovan@profusion.mobi>

Those locks are not shared between interrupt and process context anymore,
so remove the part that disable interrupts. We are still safe because
preemption is disabled.
