Luiz Augusto von Dentz 5fbc87fea2 Bluetooth: Disconnect if E0 is used for Level 4 
commit 8746f135bb01872ff412d408ea1aa9ebd328c1f5 upstream.

E0 is not allowed with Level 4:

BLUETOOTH CORE SPECIFICATION Version 5.2 | Vol 3, Part C page 1319:

  '128-bit equivalent strength for link and encryption keys
   required using FIPS approved algorithms (E0 not allowed,
   SAFER+ not allowed, and P-192 not allowed; encryption key
   not shortened'

SC enabled:
