mm/damon/stat: use secs_to_jiffies() instead of msecs_to_jiffies()

The conversion of a duration expressed in seconds reads as
msecs_to_jiffies(5 * MSEC_PER_SEC), which obscures the intent and
needlessly goes through milliseconds.  Use the dedicated secs_to_jiffies()
helper, which expresses the 5-second refresh interval directly.  No
functional change.

Found using Coccinelle (scripts/coccinelle/misc/secs_to_jiffies.cocci).
