Subject: memcg: get rid of swapaccount leftovers
swapaccount kernel parameter without any values has been removed by
a2c8990a ("memsw: remove noswapaccount kernel parameter") but it seems
that we didn't get rid of all the left overs.
Make sure that menuconfig help text and kernel-parameters.txt are clear
about value for the paramter and remove the stalled comment which is not
very much useful on its own.
