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).
