Message:

[process] fix undefined/declared variable in process_register_thread.

We made a typo.

Found with GCC:

kern/process.c: In function 'process_register_thread':
kern/process.c:1054:7: warning: 'type' may be used uninitialized in this function [-Wmaybe-uninitialized]

if( type == THREAD_IDLE ) spinlock_lock_busy( &process->th_lock , &save_sr );
