Sergey Sharybin 5ff132182d Cycles: Code cleanup, spaces around keywords
This inconsistency drove me totally crazy, it's really confusing
when it's inconsistent especially when you work on both Cycles and
Blender sides.

Shouldn;t cause merge PITA, it's whitespace changes only, Git should
be able to merge it nicely.
