[ Upstream commit 3a30964a ]

The driver may not be able to disable the ring through firmware
when downing the netdev during reset process, which may cause
hardware accessing freed buffer problem.

This patch delays the ring buffer clearing to reset uninit
process because hardware will not access the ring buffer after
hardware reset is completed.
