[PATCH 1/6] Bluetooth: mgmt: Change ordering of cmd_status paramters

[johan.hedberg]

From: Johan Hedberg <johan.hedberg@intel.com>

In accordance to the latest mgmt API specification the opcode comes
first and then the status.

[PATCH 2/6] Bluetooth: mgmt: Move status parameters into the cmd_complete header

[johan.hedberg]

From: Johan Hedberg <johan.hedberg@intel.com>

Instead of having status paramters part of each individual command
response it's simpler to just have the status as part of the command
complete header. This patch updates the code to follow this convention
and thereby also ensures compliance with the latest mgmt API
specification.
