[PATCH 4/4] be2net: disable TX in be_close()

[Sathya Perla <sathya.perla@emulex.com>]

be_close() followed by be_clear() is called as a part of cleanup in the
EEH/AER flow.  This patch stops TX in be_close() before cleaning/freeing
up the TX queues in be_clear(). This prevents be_xmit() from being called
while TX queues no longer exist.
