mm/vmalloc: add more comments to the adjust_va_to_fit_type()
When fit type is NE_FIT_TYPE there is a need in one extra object.
Usually the "ne_fit_preload_node" per-CPU variable has it and
there is no need in GFP_NOWAIT allocation, but there are exceptions.
This commit just adds more explanations, as a result giving
answers on questions like when it can occur, how often, under
which conditions and what happens if GFP_NOWAIT gets failed.
