scsi: megaraid_sas: Increase timeout by 1 sec for non-RAID fastpath IOs
[ Upstream commit 3239b8cd28fd849a2023483257d35d68c5876c74 ]
Hardware could time out Fastpath IOs one second earlier than the timeout
provided by the host.
For non-RAID devices, driver provides timeout value based on OS provided
timeout value. Under certain scenarios, if the OS provides a timeout
value of 1 second, due to above behavior hardware will timeout
immediately.
Increase timeout value for non-RAID fastpath IOs by 1 second.
