Subject: scsi: megaraid_sas: Remove redundant variable cmd_type
Patch-mainline: v6.0-rc1
Git-commit: 6464d5b8a2768e8ff63d24b76299fe614e205aa7
References: jsc#PED-1490

The variable cmd_type is assigned a value but it is never read. The
variable and the assignment are redundant and can be removed.

Cleans up clang scan build warning:

 drivers/scsi/megaraid/megaraid_sas_fusion.c:3228:10: warning: Although
 the value stored to 'cmd_type' is used in the enclosing expression, the
 value is never actually read from 'cmd_type' [deadcode.DeadStores]
