flash_protect: check for NULL flash info

If a flash is unable to be detected, and then someone calls flash_protect
on it (like the common code does in flash_init), the flash_protect logic
will dereference a NULL pointer.

Since flash_protect already does sanity checking on the info structs, add
a NULL pointer check in there.
