mm: memcg/slab: fix slab statistics in !SMP configuration
Since commit ea426c2a7de8 ("mm: memcg: prepare for byte-sized vmstat
items") the write side of slab counters accepts a value in bytes and
converts it to pages. It happens in __mod_node_page_state().
However a non-SMP version of __mod_node_page_state() doesn't perform
this conversion. It leads to incorrect (unrealistically high) slab
counters values. Fix this by adding a similar conversion to the non-SMP
version of __mod_node_page_state().
