Bluetooth: mgmt: Add local name information to read_info reply

This patch adds the name of the adapter to the reply of the read_info
management command.

The management messages reserve 249 bytes for the name instead of 248
(like in the HCI spec) so that there is always a guarantee that it is
nul-terminated. That way it can safely be passed onto string
manipulation functions.
