mm: memcg: remove redundant seq_buf_has_overflowed()
Both the end of memory_stat_format() and memcg_stat_format() will call
WARN_ON_ONCE(seq_buf_has_overflowed()). However, memory_stat_format() is
the only caller of memcg_stat_format(), when memcg is on the default
hierarchy, seq_buf_has_overflowed() will be executed twice, so remove the
redundant one.
