[PATCH] knfsd: nfsd4: clarify units of COMPOUND_SLACK_SPACE
A comment here incorrectly states that "slack_space" is measured in words, not
bytes. Remove the comment, and adjust a variable name and a few comments to
clarify the situation.
This is pure cleanup; there should be no change in functionality.
