nfp: don't wait for resources indefinitely
There is currently no timeout to the resource and lock acquiring
loops. We printed warnings and depended on user sending a signal
to the waiting process to stop the waiting. This doesn't work
very well when wait happens out of a work queue. The simplest
example of that is PCI probe. When user loads the module and card
is in a broken state modprobe will wait forever and signals sent
to it will not actually reach the probing thread.
Make sure all wait loops have a time out. Set the upper wait time
to 60 seconds to stay on the safe side.
