@verbose was added to ata_reset_fn_t because AHCI complained during
probing if no device was attached to the port. However, muting
failure message isn't the correct approach. Reset methods are
responsible for detecting no device condition and finishing
successfully. Now that AHCI softreset is fixed, kill @verbose.
