[PATCH] sysctl: fix proc_doulongvec_ms_jiffies_minmax()

[Eric Dumazet]

From: Eric Dumazet <edumazet@xxxxxxxxxx>

We perform the conversion between kernel jiffies and ms only
when exporting kernel value to user space.

We need to do the opposite operation when value is written
by user.

Only matters when HZ != 1000
