Fredrik Noring d6c931ea32 USB: OHCI: Fix NULL dereference in HCDs using HCD_LOCAL_MEM 
Scatter-gather needs to be disabled when using dma_declare_coherent_memory
and HCD_LOCAL_MEM. Andrea Righi made the equivalent fix for EHCI drivers
in commit 4307a28eb0 "USB: EHCI: fix NULL pointer dererence in HCDs

The following NULL pointer WARN_ON_ONCE triggered with OHCI drivers:
