EDAC/device: Fix period calculation in edac_device_reset_delay_period()
commit e84077437902ec99eba0a6b516df772653f142c7 upstream.
Fix period calculation in case user sets a value of 1000. The input of
round_jiffies_relative() should be in jiffies and not in milli-seconds.
[ bp: Use the same code pattern as in edac_device_workq_setup() for
clarity. ]
Fixes: c4cf3b454eca ("EDAC: Rework workqueue handling")
