[PATCH v2 3/3] scsi: aic7xxx: return negative error codes in aic7770_probe()

[Su Hui <suhui@nfschina.com>]

aic7770_config() returns both negative and positive error code.
it's better to make aic7770_probe() only return negative error codes.

And the previous patch made ahc_linux_register_host() return negative error
codes, which makes sure aic7770_probe() returns negative error codes.
