libata: prevent devices with blank model names from being DMA blacklisted
The strn_pattern_cmp routine does not handle a blank name parameter properly. The only patterns which should match a blank name are "*" and an explicit "". If the function is passed a blank name in current code, it will always match against the patt parameter. The bug manifests itself as the device with the empty model name always matching the first device in the DMA blacklist, forcing it to revert to PIO mode.
