Driver APIs might not implement all operations, making it possible for a user thread to get the kernel to execute a function at 0x00000000. Perform runtime checks in all the driver handlers, checking if they're capable of performing the requested operation. Fixes #6907. Signed-off-by: Leandro Pereira <leandro.pereira@intel.com>
