msm: camera: use correct instance of local queue pointer.

There is a bug in the msm_open error handling, where the clean-up
is being done on a 'function level' instance of a pointer,
whereas the initialization is done on an 'if level' instance in
the same function. This change removes the 'if level' instance.
