Using NETDEV_TX_BUSY is tricky. Its meant for situations where the error
in question is transient and quickly resolved. But the driver rarely is
able to know that to a certainty. And in the case of visornic, it just
uses it without any care for that, in the hopes that it won't loose frames,
even if the problem is that the skb is somehow malformed for the hardware.
If we get one of those kinds of skbs, NETDEV_TX_BUSY will just cause us to
spin, processing the same error over and over.
Fix it by dropping the frame, stopping the queue where appropriate, and
returning NETDEV_TX_OK

As pointed out in a recent review, the num_visornic_open array didn't do
anything useful, and it exposed a potential race in the visornic code that
could arise while taking down a net interface while reading from the
debugfs files. Fix that by removing the array entirely, and just iterating
over all the registered netdevs in a given namespace, filtering on them
having visornic ops (to identify which are ours), and having their queues
not be stopped (identifying that they are up). This should prevent any oops
conditions happening due to changing state in that array, and save us a
bunch of code too.

Smatch complains because "delba" is a pointer to struct
rtl_80211_hdr_3addr so the "delba += sizeof(struct rtl_80211_hdr_3addr);"
is clearly wrong. We are reading nonsense data from beyond the end of
the buffer and could oops if that memory isn't mapped.
It turns out the next two statements are also wrong. We should delete
the += sizeof() statement and "delba+2" should be "&delba->payload[2]".
"pReasonCode" isn't used so I deleted that.
