[PATCH 5.10 38/64] EDAC/device: Fix period calculation in edac_device_reset_delay_period()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Eliav Farber <farbere@amazon.com>

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")
