Sonny Sasaka 89e65975fe Bluetooth: Cancel Inquiry before Create Connection 
Many controllers do not allow HCI Create Connection while it is doing
Inquiry. This patch adds Inquiry Cancel before Create Connection in this
case to allow the controller to do Create Connection. User space will be
aware of this Inquiry cancellation and they may issue another discovery
request afterwards.

Sample Command Disallowed response of HCI Create Connection:
< HCI Command: Inquiry (0x01|0x0001) plen 5
        Access code: 0x9e8b33 (General Inquiry)
        Length: 10.24s (0x08)
        Num responses: 0
> HCI Event: Command Status (0x0f) plen 4
      Inquiry (0x01|0x0001) ncmd 2
        Status: Success (0x00)
< HCI Command: Create Connection (0x01|0x0005) plen 13
        Address: XX:XX:XX:XX:XX:XX
        Packet type: 0xcc18
        Page scan repetition mode: R2 (0x02)
        Page scan mode: Mandatory (0x00)
        Clock offset: 0x0000
        Role switch: Allow slave (0x01)
> HCI Event: Command Status (0x0f) plen 4
      Create Connection (0x01|0x0005) ncmd 1
        Status: Success (0x00)
> HCI Event: Connect Complete (0x03) plen 11
        Status: Command Disallowed (0x0c)
        Handle: 65535
        Address: XX:XX:XX:XX:XX:XX
        Link type: ACL (0x01)
