dma-buf: heaps: Fix the name used when exporting dmabufs to be the actual heap name
By default dma_buf_export() sets the exporter name to be
KBUILD_MODNAME. Unfortunately this may not be identical to the
string used as the heap name (ie: "system" vs "system_heap").
This can cause some minor confusion with tooling, and there is
the future potential where multiple heap types may be exported
by the same module (but would all have the same name).
So to avoid all this, set the exporter exp_name to the heap name.
