[SCSI] kill scsi host template suspend/resume
With libata converted to use sdev->manage_start_stop for suspend and resume, sht->suspend/resume() has no user left and low level suspend/ressume should be taken care of by low level driver's suspend/resume callbacks (e.g. PCI or PCMCIA driver callbacks). This patch removes sht->suspend/resume() callbacks. This change is suggested by Christoph Hellwig.
