locking/x86: Drop a comment left over from X86_OOSTORE

The comment about wmb being non-NOP to deal with non-Intel CPUs
is a left over from before the following commit:

  09df7c4c8097 ("x86: Remove CONFIG_X86_OOSTORE")

It makes no sense now: in particular, wmb() is not a NOP even for
regular Intel CPUs because of weird use-cases e.g. dealing with
WC memory.

Drop this comment.
