[SCSI] megaraid_sas: zcr with fix

The patch adds support for a ZCR controller (Device ID : 0x413).

It also has a critical bug fix :

Disable controller interrupt before firing INIT cmd to FW.  Interrupt
is enabled after required initialization is over. This is done to
ensure that driver is ready to handle interrupts when it is generated
by the controller.
