@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.
