commit eca94432934fe5f141d084f2e36ee2c0e614cc04 upstream.

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")
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=203997
