tools: ynl: ethtool: use doit instead of dumpit for per-device GET

Rename the local helper doit() to do_set() and dumpit() to do_get() to
better reflect their purpose.

Convert do_get() to use ynl.do() with an explicit device header instead
of ynl.dump() followed by client-side filtering. This is more efficient
as the kernel only processes and returns data for the requested device,
rather than dumping all devices across the netns.
