[PATCH AUTOSEL 6.6 06/20] usbnet: ipheth: do not stop RX on failing RX callback

[Sasha Levin <sashal@kernel.org>]

From: Foster Snowhill <forst@pen.gy>

[ Upstream commit 74efed51e0a4d62f998f806c307778b47fc73395 ]

RX callbacks can fail for multiple reasons:

* Payload too short
* Payload formatted incorrecly (e.g. bad NCM framing)
* Lack of memory

None of these should cause the driver to seize up.

Make such failures non-critical and continue processing further
incoming URBs.
