[SCSI] mpt2sas: Don't disable device twice at suspend.
On suspend, _scsih_suspend calls mpt2sas_base_free_resources, which in turn calls pci_disable_device if the device is enabled prior to suspending. However, _scsih_suspend also calls pci_disable_device itself. Thus, in the event that the device is enabled prior to suspending, pci_disable_device will be called twice. This patch removes the duplicate call to pci_disable_device in _scsi_suspend as it is both unnecessary and results in a kernel oops.
