USB: omninet: fix write_room

Browse Source 
commit 694c6301e5 upstream.

Fix regression introduced by commit 507ca9bc04 ([PATCH] USB: add
ability for usb-serial drivers to determine if their write urb is
currently being used.) which inverted the logic in write_room so that it
returns zero when the write urb is actually free.
