Bluetooth: SMP: Convert BT_ERR/BT_DBG to bt_dev_err/bt_dev_dbg

Commit Message

Luiz Augusto von Dentz March 11, 2021, 9:18 p.m. UTC

From: Luiz Augusto von Dentz <[e-mail]>

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.
