Subject: [PATCH 4.19 047/149] scsi: lpfc: Correct localport timeout duration error

From: James Smart <jsmart2021@...il.com>

[ Upstream commit 2a0fb340fcc816975b8b0f2fef913d11999c39cf ]

Current code incorrectly specifies a completion wait timeout duration in 5
jiffies, when it should have been 5 seconds.

Fix the adjust for units for the completion timeout call.

[mkp: manual merge]
