sched/mqueue/mq_notify.c: Fix - only part of struct copied to internal structure

As source adress the adress of the struct member sigev_value was used,
and it is not located the start of the struct.
This leads to invalid data being copied to internal structure.
Both source and destination should be of type struct sigevent* .
