[RFC 2/8] gattrib: Fix g_attrib_set_mtu

[Andre Guedes <andre.guedes@xxxxxxxxxxxxx>]

23 octets is the default (and minimum) ATT_MTU value. If someone tries
to set ATT_MTU less than 23 octets g_attrib_set_mtu should fail (return
FALSE). Additionally, there is no constraint regarding the maximum value
of ATT_MTU, so we should not check for it.

Also, we should not change the L2CAP ATT fixed channel MTU. bt_io_set
call will always fail since we are not supposed to change L2CAP MTU
after connection is established.
