Subject: [PATCH v2]PM/wakeup: Add print_wakeup_source_stats(m, &deleted_ws)

From: zhuguangqing <zhuguangqing@...omi.com>

After commit 00ee22c28915 (PM / wakeup: Use seq_open()
to show wakeup stats), print_wakeup_source_stats(m, &deleted_ws)
is deleted in function wakeup_sources_stats_seq_show().

Because deleted_ws is one of wakeup sources, so it should
also be showed. This patch add it to the end of all other
wakeup sources.
