[general] Fixed crash in fs.h, when called with fsdrv.create == NULL 

When a nor0 devices has no partitions assigned, then a call to
open() to create a file will jump with a NULL fct ptr.

Much more cheching code is missing and pointers to function are
jumped without any NULL ptr check. This must be fixed as well later.
