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 up, keeping the consistency with the other sections of the text.

raw_spinlock_t is a strict spinning lock implementation regardless of the
kernel configuration including PREEMPT_RT enabled kernels.
raw_spinlock_t is a strict spinning lock implementation in all kernels,
including PREEMPT_RT kernels. Use raw_spinlock_t only in real critical
