This code has never worked correctly, doesn't disable interrupts when
set as a module parameter, doesn't disable interrupts when set after
driver load time in sysfs node, etc.

The following patch for megaraid_sas will fix a potential bad pointer access
in megasas_reset_timer(), when a MegaRAID 9265/9285 or 9360/9380 gets a
timeout. megasas_build_io_fusion() sets SCp.ptr to be a struct
megasas_cmd_fusion *, but then megasas_reset_timer() was casting SCp.ptr to be
a struct megasas_cmd *, then trying to access cmd->instance, which is invalid.
Just loading instance from scmd->device->host->hostdata in
megasas_reset_timer() fixes the issue.

The following patch for megaraid_sas adds a driver workaround for
PERC5/1068 based controller FW that keeps a command from the main
kernel that the driver cannot cancel which was causing a kernel panic
in shutdown of the kdump kernel.

Simple conversions to drop flush_scheduled_work() usages in

flush_scheduled_work() -> cancel_delayed_work_sync().
* mpt2sas_scsih: drop unnecessary flush_scheduled_work().

using flush_scheduled_work().
