IDE: Report errors during drive reset back to user space
Make sure that each error condition during the execution of an HDIO_DRIVE_RESET ioctl is actually reported to the calling process. Also, unify the exit path of reset_pollfunc() when returning ide_stopped since the need of ->port_ops->reset_poll() to be treated specially has vanished (way back, it seems).
