Bluetooth: Avoid a case where sleep is getting called in soft irq context

While turning off BT, sleep is getting called in the soft isr context
from work queue which is queued from a code section guarded under the
bh lock,
To resolve this released the bh lock before queing the work, as it wont
impact any BT functionality.
