bluetooth: Avoid duplicating profile argument twice
The module module-bluetooth-device should never be given parameter
'profile' twice, even if both HFGW and A2DP are playing. This patch
proposed to consider HFGW first.

bluetooth: Consider different input and output MTU
Previous implementation assumes these values are equal, but this doesn't
necessarily have to be so.
