Documentation: Fix duplicate statement about raw_spinlock_t type
Unless it was duplicate on purpose, to emphasize that a raw_spinlock_t is always a spinning lock regardless of PREEMPT_RT or kernel config, it's a bit odd that this text is duplicate. So, this patch just clean it up, keeping the consistency with the other sections of the text.
