This changes the handling of an unlikely condition to not stop dequeuing if taprio failed to dequeue the peeked skb in taprio_dequeue(). I've no idea when this can happen, but the only side effect seems to be that the atomic_sub_return() call right above will have consumed some budget. This isn't a big deal, since either that made us remain without any budget (and therefore, we'd exit on the next peeked skb anyway), or we could send some packets from other TXQs. I'm making this change because in a future patch I'll be refactoring the dequeue procedure to simplify it, and this corner case will have to go away.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
