Bluetooth: Fix faulty expression for minimum encryption key size check
Fix minimum encryption key size check so that HCI_MIN_ENC_KEY_SIZE is
also allowed as stated in the comment.
This bug caused connection problems with devices having maximum
encryption key size of 7 octets (56-bit).
Fixes: 693cd8ce3f88 ("Bluetooth: Fix regression with minimum encryption key size alignment")
