Subject: liquidio: make timeout HZ independent and readable
Patch-mainline: v4.18-rc6
Git-commit: 7481a8576ad87ac92526a931c0cd5733db7c1250
References: bsc#1119406 FATE#326562

schedule_timeout_* takes a timeout in jiffies but the code currently is
passing in a constant which makes this timeout HZ dependent. So define
a constant with (hopefully) meaningful name and pass it through
msecs_to_jiffies() to fix the HZ dependency.
