[PATCH] usb gadget: ethernet/rndis updates

Updates to the Ethernet/RNDIS gadget driver (mostly for RNDIS):

  - Fix brown-paper bag goof with RNDIS packet TX ... the wrong length
    field got set, so Windows would ignore data packets it received.

  - More consistent handling of CDC output filters (but not yet hooking
    things up so RNDIS uses the mechanism).

  - Zerocopy RX for RNDIS packets too (saving CPU cycles).

  - Use the pre-allocated interrupt/status request and buffer, rather
    than allocating and freeing one of each every few seconds (which
    could fail).

  - Some more "sparse" tweaks, making both dual-speed and single-speed
    configurations happier.

  - RNDIS speeds are reported in units of 100bps, not bps.

Plus two minor cleanups (whitespace, messaging).
