The VIDIOC_G_STD ioctl may not be present in the case of radio receivers.
In that case G_STD will return an error. The v4l1-compat layer should not
attempt to propagate that error to the caller, instead it should be
ignored.

In some cases we're seeing large timeouts on commands. I'm changing the
implementation so that the deferred worker checks the PCI bus for
any messages and signals the waiting caller accordingly. The previous
mechanism was too unreliable.

The firmware typically responds in < 50ms and, via the interrupts and
deferred work queue the caller (blocked in the driver) is signalled very
efficiently. In a highly stressed system this can take many multiples
of seconds. So, we need a larger maximum timeout for busy systems.
