mlx4_core: Change command token on timeout The FW command token is currently only updated on a command completion event. This means that on command timeout, the same token will be reused for new command, which results in a mess if the timed out command *does* eventually complete.

This is the same change as the patch for mthca from Michael
S. Tsirkin <[e-mail]> that was just merged. It seems
sensible to avoid gratuitous differences in FW command processing
between mthca and mlx4.
