c-user: Remove RTEMS_MP_NOT_CONFIGURED error
Some objects can be created with a local or global scope in a multiprocessing network. In non-multiprocessing configurations setting the scope to local or global had no effect since such a system can be viewed as a multiprocessing network with just one node. One and all nodes is the same in such a network. However, if multiprocessing was configured, creation of a global object in a single node network resulted in an RTEMS_MP_NOT_CONFIGURED error. Remove this error condition for symmetry to the non-multiprocessing setup. This is in line with the task affinity behaviour in SMP systems. Close #4005.
