Bluetooth: btusb: add a reject table to disable msft
With Intel AC9560, follow this scenario and can't turn on bt since.
1. turn off BT
2. then suspend&resume multiple times
3. turn on BT

Get this error message after turn on bt.
[ 877.194032] Bluetooth: hci0: urb 0000000061b9a002 failed to resubmit (113)
[ 886.941327] Bluetooth: hci0: Failed to read MSFT supported features (-110)

Remove msft from compilation would be helpful.
Turn off msft would be also helpful.

As per Intel's comment, For AC9560, in JSL the hw_variant is 0x13.
In GLK, the hw_variant is 0x11. can't use hw_variant to filter for
AC9560.
Only AC9560 encounter this issue, so add a reject table to
disable msft for AC9560.
