FROMGIT: Bluetooth: Check inquiry status before sending one
There is a possibility where HCI_INQUIRY flag is set but we still
send HCI_OP_INQUIRY anyway.
Such a case can be reproduced by connecting to an LE device while
active scanning. When the device is discovered, we initiate a
connection, stop LE Scan, and send Discovery MGMT with status
disabled, but we don't cancel the inquiry.
BUG=b:180148986
TEST=Do these steps.
(1) Start active scan
(2) Within 10 seconds, scan and establish a successful connection to
a before unpaired LE device. If 10 seconds has passed, we are
not 'actively' scanning anymore, so remove the device and retry.
(3) Verify no "Command Disallowed" in btsnoop log.
