rtems: Change rtems_task_get_affinity() status

In case the processor set is not large enough to contain the processor
affinity set of the task return RTEMS_INVALID_SIZE instead of
RTEMS_INVALID_NUMBER. This is more in line with other directives since
the issue is related to the size of an object.

Close #4393.
