scsi: libsas: Change the coding style of sas_discover_sata()
The coding style where calling this interface is inconsistent with other
interfaces for SATA devices. The standard style for other SATA interfaces
is like:
#ifdefine CONFIG_SCSI_SAS_ATA
void sas_ata_task_abort(struct sas_task *task);
#else
static inline void sas_ata_task_abort(struct sas_task *task)
{
}
#endif
And the callers does not have to do things like "#ifdefine CONFIG_SCSI_SAS_ATA"
and may call the interface directly. So follow the standard style here.
