scsi: libsas: Remove postreset from sas_sata_ops

Browse Source 
sas_sata_ops uses ata_std_postreset as .postreset callback. However,
ata_std_postreset() calls sata_scr_read()/sata_scr_write() which need to
access the ATA SCR register. This register not available in the libsas case
and the functions always return -EOPNOTSUPP.

Drop the .postreset callback.
