HDP: reject MDL reconnection with different MTU

This patch implements refusal of a MDL reconnection if the new L2CAP
connection presents a different MTU. Accordingly to HDP spec. item 3.5.

It aims to pass the TC_SNK_HCT_BV_07_C PTS test. (It does not pass yet
because PTS itself seems to have issues. See tickets 7212, 7214 and
7244 for details.)
