The recent be2net commit 6384a4d0 (adds a support for busy polling)
introduces a regression that results in kernel crash. It incorrectly
modified be_close() so napi_disable() is called only for the first queue.
This breaks a correct pairing of napi_enable/_disable for the rest
of event queues and causes a crash in subsequent be_open() call.
