staging/ozwpan: Fix NULL vs zero in ozusbsvc1.c (sparse warning)
This patch fixes the warning "Using plain integer as NULL pointer", generated by sparse, by replacing the offending 0s with NULL. If the initialization with NULL was unnecessary (due to unconditional assignment before first use) it was removed.
