This patch seems to break avctp browsing. The creation of browsing_io in
avctp_register already uses L2CAP_MODE_ERTM which is not in the
switch-case hence results in "Unsupported mode". What is the desired way
to fix this? Should all those calls use BT_IO_MODE_* instead? Not to
mention the uses of these functions should be checked for their enum
usage as well.
