mm: memcontrol: clarify swapaccount=0 deprecation warning
commit 118642d upstream. The swapaccount deprecation warning is throwing false positives. Since we deprecated the knob and defaulted to enabling, the only reports we've been getting are from folks that set swapaccount=1. While this is a nice affirmation that always-enabling was the right choice, we certainly don't want to warn when users request the supported mode. Only warn when disabling is requested, and clarify the warning.
