[PATCH 2.6 1/3] e100: stepping over err return code

[Scott Feldman <scott.feldman@xxxxxxxxx>]

* Spotted by Jay Vosburgh [fubar@xxxxxxxxxx].  err return code was getting
stepped on in the case where we need to report low or no cb resources,
which in turn messed up the netif_stop_queue logic in xmit_frame.
