[SCSI] aacraid: apply commit config for reset_devices flag

Under some conditions associated with the unclean transition to kdump,
the aacraid adapters will view the array as foreign and not export it to
prevent access and data manipulation. The solution is to submit a commit
configuration to export the devices since this is a expected behavior
when transitioning to a kdump kernel.

This patch adds the aacraid.reset_devices flag and when either this or
the global reset_devices flag is set, ensures that a commit config is
issued and extends the startup_timeout if it is set less than 5 minutes.
