[PATCH 2/3] megaraid_sas: Increase timeout by 1 sec for non-RAID fastpath IOs

[Shivasharan S]

Problem description:
Hardware could timeout 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.

Fix:
Increase timeout value for non-RAID fastpath IOs by 1second.
