once: rename _SLOW to _SLEEPABLE

Browse source 
The _SLOW designation wasn't really descriptive of anything. This is
meant to be called from process context when it's possible to sleep. So
name this more aptly _SLEEPABLE, which better fits its intended use.

Fixes: 62c07983be ("once: add DO_ONCE_SLOW() for sleepable contexts")
