Subject: net: ethoc: enable NAPI before poll may be scheduled

From: Max Filippov <[email protected]>

[ Upstream commit d220b942a4b6a0640aee78841608f4aa5e8e185e ]

ethoc_reset enables device interrupts, ethoc_interrupt may schedule a NAPI poll before NAPI is enabled in the ethoc_open, which results in device being unable to send or receive anything until it's closed and reopened. In case the device is flooded with ingress packets it may be unable to recover at all.
Move napi_enable above ethoc_reset in the ethoc_open to fix that.
