Subject: [PATCH] smartpqi: Fix timeout of smartpqi probe stage

I use 'HPE Smart Array E208i-a SR Gen10 Controller', and pass through
the SAS controller from ESXi 6.0U1 to VM, which is installed CentOS 7.4/7.5.
The disk is not found.

The error log is "controller not ready after 30 seconds."

Add some logs, and could check the probe stage needs nearly 36s to match the
status.
