    upcall: Resolve dict leak from up_(f)removexattr in upcall code path

    Problem: In up_(f)removexattr() dict_for_key_value() is used to create a
             new dict. This dict is not correctly unref'd and gets leaked.

    Solution: To avoid the leak up_(f)removexattr() now also does a
              dict_unref() on the newly created dict.

    While reviewing the code in up_(f)setxattr() for a similar problem, it
    was noticed that there is an extra dict created. There is no need for
    this copy, upcall_local_init() can just take the dict that was passed as
    argument to the FOP.
