Subject: [PATCH] scsi: smartpqi_init: fix boolean expression in pqi_device_remove_start


Fix boolean expression by using logical AND operator '&&'
instead of bitwise operator '&'.

This issue was detected with the help of Coccinelle.

Fixes: 1e46731efd9c ("scsi: smartpqi: check for null device pointers")

Thanks for the update.
