mm/compaction.c: __compact_pgdat() code cleanuup

Browse source 
This patch uses is_via_compact_memory() to distinguish compaction from
sysfs or sysctl.  And, this patch also reduces indentation on
compaction_defer_reset() by filtering these cases first before checking
watermark.

There is no functional change.
