dma-buf: Do not build debugfs related code when !CONFIG_DEBUG_FS

Browse source

There is no point in compiling in the list and mutex operations which are
only used from the dma-buf debugfs code, if debugfs is not compiled in.

Put the code in questions behind some kconfig guards and so save some text
and maybe even a pointer per object at runtime when not enabled.
