ata: libata: Rename ata_eh_read_sense_success_ncq_log()

The function ata_eh_read_sense_success_ncq_log() does more that just
reading the sense data for successful NCQ commands log page as it also
sets the sense data for all commands listed in the log page.

Rename this function to ata_eh_get_ncq_success_sense() to better
describe what the function does. Furthermore, since this function is
only called from ata_eh_get_success_sense() in libata-eh.c, there is no
need to export it and its declaration can be moved to
drivers/ata/libata.h.

To be consistent with this change, the function
ata_eh_read_sense_success_non_ncq() is also renamed to
ata_eh_get_non_ncq_success_sense().
