[PATCH] sata_sis: fix flags handling for the secondary port

sis_init_one() modifies probe_ent->port_flags after allocating and
initializing it using ata_pci_init_native_mode().  This makes port_flags
for the secondary port (probe_ent->pinfo2->flags) go out of sync resulting
in misdetection of device due to incorrectly initialized SCR access flag.

This patch make probe_ent alloc/init happen after the final port flags
value is determined.  This is fragile but probe_ent and all the related
mess are scheduled to go away soon for exactly this reason.  We just need
to hold everything together till then.

This has been spotted and diagnosed and tested by Patrick McHardy.
