Bluetooth: mgmt: Fix the command returns garbage parameter value

Browse source 
[ Upstream commit 02ce2c2c24 ]

When the Get Device Flags command fails, it returns the error status
with the parameters filled with the garbage values. Although the
parameters are not used, it is better to fill with zero than the random
values.
