This patch will fix regression caused by below commit-
1e793f6 scsi: megaraid_sas: Fix data integrity failure for JBOD (passthrough) devices
The problem was MEGASAS_IS_LOGICAL macro does not have braces and because of above commit
using this macro was exposing lot of non-existing SCSI devices(all SCSI commands to channels-1,2,3 was
returned as SUCCESS-DID_OK by driver).
