BT on Redpine RS9113 Wifi+BT combo device stops working after the system
resumes from S4. The command:
$ hciconfig -a

fails with error:
Can't read local name on hci0: Connection timed out (110)

This patch series fixes the BT hci issues after resume from S4.

These patches are already verified by CE-QA with a test kernel based on
Ubuntu-oem-4.15.0-1005.8. Regression potential is minimal becasue, for now
this Wifi+BT card is available only on Dell Edge 300x IoT Gateways.

  UBUNTU: SAUCE: Bluetooth: btrsi: add hci detach for hibernation and poweroff
  UBUNTU: SAUCE: Bluetooth:btrsi: add null check in hci send and recv functions
  UBUNTU: SAUCE: Bluetooth:btrsi: fix bt cmd timeout issue
