Laurent Pinchart 496e4467d2 libcamera: control_serializer: Fix usage of uninitialized variable ...

The idMap variable may be used uninitialized in the
ControlSerializer::deserialize<ControlList>() function as reported by
gcc 11:

../../src/libcamera/control_serializer.cpp: In member function ‘T libcamera::ControlSerializer::deserialize(libcamera::ByteStreamBuffer&) [with T = libcamera::ControlList]’:
../../src/libcamera/control_serializer.cpp:609:33: error: ‘idMap’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
  609 |         ControlList ctrls(*idMap);
      |

This is due to a missing default case in a switch/case. Fix it by adding
the default case.
