[PATCH 13/13] USBATM: -EILSEQ workaround

[Duncan Sands <baldrick@free.fr>]

Don't throttle on -EILSEQ urb status if requested by a minidriver.
It seems the ueagle modems are buggy, giving -EILSEQ when they
have no data to send.  The ueagle change will be sent separately
by the ueagle guys.  Patch by Matthieu Castet.
