be2net: fix wrong frag_idx reported by RX CQ
The RX CQ can report completions with invalid frag_idx when the RXQ that was *previously* using it, was not cleaned up properly. This hits a BUG_ON() in be2net. When completion coalescing is enabled on a CQ, an explicit CQ-notify (with rearm) is needed for each compl, to flush partially coalesced CQ entries that are pending DMA. In be_close(), this fix now notifies CQ for each compl, waits explicitly for the flush compl to arrive and complains if it doesn't arrive. Also renaming be_crit_error() to be_hw_error() as it's the more appropriate name and to convey that we don't wait for the flush compl only when a HW error has occurred.
