scsi: aic7xxx: Return ahc_linux_register_host()'s value rather than zero

ahc_linux_register_host() can return an error code in case of failure. So
ahc_linux_pci_dev_probe() should return the value of
ahc_linux_register_host() rather than zero.

An earlier commit made ahc_linux_register_host() return negative error
codes, which makes sure ahc_linux_pci_dev_probe() returns negative error
codes.
