[libata sata_nv] fix dev detect by removing sata-reset flag

Remove ATA_FLAG_SATA_RESET.  See comment in code and
http://bugme.osdl.org/show_bug.cgi?id=3352 for more details.

This problem needs more investigation.  Removing the flag
appears to fix the problems in the field, so it's the best
temporary solution.
