Subject: [PATCH 3.15 086/139] Bluetooth: Fix missing check for FIPS security level

3.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hedberg <johan.hedberg@...el.com>

commit f3fb0b58c85666f73139963a7a04d7878f3d22c9 upstream.

When checking whether a legacy link key provides at least HIGH security
level we also need to check for FIPS level which is one step above HIGH.
This patch fixes a missing check in the hci_link_key_request_evt()
function.
