Subject: [PATCH] rbd: make const pointer speaces a static const array

Don't populate the const array spaces on the stack but make it static
const and make the pointer an array to remove a dereference. Shrinks
object code a little too.  Also clean up intent, currently it is spaces
and should be a tab.
