[RFC BlueZ 1/2] A2DP: Mark start flag if resume happen while in configured state

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

If SEP is in configured state that means OPEN is about to happen so just
mark start flag and send START once OPEN completes.
