kernel: Move flag_ipi() into z_set_prio()

Moves a call to flag_ipi() from z_thread_priority_set() into z_set_prio(). This allows for an IPI to be done for a thread that had its priority bumped due to the handling of priority inheritance from a mutex. Incidentally, all calls to flag_ipi() are now performed with sched_spinlock being locked. Signed-off-by: Peter Mitsis <[email protected]>
