From: Johan Hedberg <johan.hedberg@xxxxxxxxx>
HCI devices in RAW mode will have the HCI_UP flag set. The existing
hci_sock_bind code, when invoked on a HCI_CHANNEL_USER socket, tests
for this flag and will return EBUSY, making it impossible to bind any
HCI device RAW mode. This patch adds an extra condition for the
HCI_RAW flag to make it possible for bind() to succeed.
