Bin Meng 439fcb9b4f sf: Fix NULL pointer exception for flashes without lock methods ...

commit c3c016c "sf: Add SPI NOR protection mechanism" introduced
flash_lock()/flash_unlock()/flash_is_locked() methods for SPI flash,
but not every flash driver supplies these. We should test these
methods against NULL before actually calling them.
