Santiago Carot-Nemesio 0a39787183 Fix potential memory leak in MCAP code
Data provided by profiles using MCAP may fall in memory leak if
control channel is closed before reply arrives from remote side.
This patch add a GDestroyNotify function parameter in MCAP API
to release private data provided by upper layers even if adapter
is removed or control channels is closed before reply from remote
side arrives.
