5.6 mainline kernel also does not work.

** Description changed:
New bug report for kernel:
After testing Ubuntu 20.04 on my Intel NUC (NUC8i3BEH) I found out, that
Bluetooth (LE) [hardware: Intel Wireless-AC 9560] isn't working; hcitool lescan
reports:
hcitool lescan
Set scan parameters failed: Input/output error
When the error occurs, btmon is reporting:
> HCI Event: Command Complete (0x0e) plen 4 #4 [hci0]
20:22:26.130058
LE Set Scan Enable (0x08|0x000c) ncmd 1
Status: Command Disallowed (0x0c)
Beside the following error messages, there are no clues in the syslog
concerning the error as far as I can tell:
[ 138.152718] debugfs: File 'le_min_key_size' in directory 'hci0' already
present!
[ 138.152722] debugfs: File 'le_max_key_size' in directory 'hci0' already
present!
After testing the Ubuntu kernels I found out that this Bluetooth LE scanning
works just fine with Kernel 4.15 (Ubuntu 18.04 up to date standard kernel) and
Kernel 4.18 (Ubuntu 18.04.1 HWE EOL kernel).
The problem starts from kernel version 5.0 (Ubuntu 18.04.2 HWE kernel) and is
reproducible with the current Ubuntu 20.04 standard kernel.
