scsi: lpfc: Correct maximum PCI function value for RAS fw logging

Currently, the ras_fwlog_func sysfs parameter allows users to input a value
greater than three when selecting a PCI function to enable RAS fw logging
feature.

The user's input is sanity checked in lpfc_sli4_ras_init(), but allowing an
input greater than three doesn't make sense because the max number of ports
per HBA is four.

Change the allowable range from [0, 7] to [0, 3].
