[PATCH] dax: include bus.h for definition of run_dax()

[Ben Dooks]

The run_dax() prototype is defined in "bus.h" but drivers/dax/super.c
does not include this. Include bus.h to silece the following sparse
warning:

drivers/dax/super.c:337:6: warning: symbol 'run_dax' was not declared. Should it be static?
