Remove BOARD_FAILED and don't save dgnc_boards which failed to

Assign the result of kzalloc() to brd in dgnc_found_board() and only put
it in the dgnc_Board[] if it successfully initializes. Also, remove
BOARD_FAILED enum and all ifs that check for it. Finally, remove one
final place where state was set to BOARD_FAILED which was even redundant
before this patch.

You've done a great job here, but...
Yeah, sorry...
I really want to see this whole "static list of boards/cards" go away.
There should not be any need for that in any in-kernel driver. Your
patch here is a sign that things are really wrong with this whole static
array mess.
So could you do that instead? I don't want to take patches around this
whole "board state" mess anymore, as it should all not be needed at all.
If you need pointers on what needs to be done here, just let me know.
thanks,

I can try :) But my main concern is the lack of dgnc driver maintainers
activity and that I don't own the hardware this driver is written for as
it's quite expensive (cheapest cards I've found start at 300$~) and I
can't afford it ATM. But I guess if I keep the patches small and logical
everything will be okay.
I am on the maintainers list and actually have hardware. I have just
been so swamped the last few months that I haven't been able to do
ANYTHING here. Even work on the dgap driver that I was working on, I
just haven't had the time. I can tell you that the dgnc driver does NOT
work at all and hasn't worked since it was introduced into staging by Greg.
Greg, while I'm here, how can we get Digi firmware into the kernel
firmware tree? The dgap card is useless without it and I suspect the
dgnc is as well.
