ata: libata: add missing ata_identify_page_supported() calls
ata_dev_config_ncq_prio() and ata_dev_config_devslp() both access pages
of the IDENTIFY DEVICE data log. Before calling ata_read_log_page(),
make sure to check for the existence of the IDENTIFY DEVICE data log and
of the log page accessed using ata_identify_page_supported(). This
avoids useless error messages from ata_read_log_page() and failures with
some LLDD scsi drivers using libsas.
