USB: omninet: fix write_room
commit 694c6301e515bad574af74b6552134c4d9dcb334 upstream.
Fix regression introduced by commit 507ca9bc047666 ([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.
