habanalabs: restore vm_pgoff after mmap
Due to using dma_mmap_coherent() to perform mmap of dma memory, we had to clear the vm_pgoff field before calling that function. However, that broke the userspace (profiler tool) as they relied on searching the /proc/self/maps for these values to correctly "disassemble" the topology recipe. To re-enable that functionality, the driver can simply restore the value of vm_pgoff before returning to userspace but after calling dma_mmap_coherent().
