Change subject: taskprocessor.c: Fix some taskprocessor unrefs.
......................................................................

taskprocessor.c: Fix some taskprocessor unrefs.

You have to call ast_taskprocessor_unref() outside of the taskprocessor
implementation code.  Taskprocessor use since v12 has become more
transient than just the singleton uses in earlier versions.
