Documentation/locking/locktypes: Update migrate_disable() bits.
commit 6a631c0432dcccbcf45839016a07c015e335e9ae upstream.
The initial implementation of migrate_disable() for mainline was a
wrapper around preempt_disable(). RT kernels substituted this with
a real migrate disable implementation.
Later on mainline gained true migrate disable support, but the
documentation was not updated.
Update the documentation, remove the claims about migrate_disable()
mapping to preempt_disable() on non-PREEMPT_RT kernels.
Fixes: 74d862b682f51 ("sched: Make migrate_disable/enable() independent of RT")
