Greetings,

There's a memory leak in net/dccp/feat.c::dccp_feat_empty_confirm().
If we hit the 'default:' case of the 'switch' statement, then we 
return without freeing 'opt', thus leaking 'struct dccp_opt_pend' 
bytes.
The leak is fixed easily enough by adding a kfree(opt); before the 
return statement.
The patch also changes the layout of the 'switch' to be more in line 
with CodingStyle.

Patch has been compile tested.

Please consider merging.
