ata: libata-eh: Do not retry reset if the device is gone

Browse Source 
If a device is hot-unplugged or otherwise disappears during error handling,
ata_eh_reset() may fail with -ENODEV. Currently, the error handler will
continue to retry the reset operation up to max_tries times.

Prevent unnecessary reset retries by exiting the loop early when
ata_do_reset() returns -ENODEV.
