[PATCH 5.10 53/75] Bluetooth: SMP: Convert BT_ERR/BT_DBG to bt_dev_err/bt_dev_dbg

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

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

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

[ Upstream commit 2e1614f7d61e407f1a8e7935a2903a6fa3cb0b11 ]

This converts instances of BT_ERR and BT_DBG to bt_dev_err and
bt_dev_dbg which can be enabled at runtime when BT_FEATURE_DEBUG is
enabled.

Note: Not all instances could be converted as some are exercised by
selftest.
