This reverts commit
1d6119baf0610f813eb9d9580eb4fd16de5b4ceb.
After reverting commit
6d7b857d541e ("net: use lib/percpu_counter API
for fragmentation mem accounting") then here is no need for this
fix-up patch. As percpu_counter is no longer used, it cannot
memory leak it any-longer.
Fixes:
6d7b857d541e ("net: use lib/percpu_counter API for fragmentation mem accounting")
Fixes:
1d6119baf061 ("net: fix percpu memory leaks")
