[SCSI] sym53c8xx: Make interrupt handler capable of returning IRQ_NONE
Make sym_interrupt return an irqreturn_t instead of void, and take a
Scsi_Host instead of a sym_hcb. Pass the Scsi_Host to the interrupt
handler instead of the sym_hcb. Rename the host_data to sym_data.
Keep a pci_dev pointer in the sym_data. Rename the Scsi_Host from
instance to shost.
