gpu: nvgpu: simplify gmmu unmap calls

Browse Source 
Introduce nvgpu_gmmu_unmap_addr() to unmap a nvgpu_mem that was mapped
at some other address than mem.gpu_va, which can be the case for buffers
that are shared across different address spaces. Delete the address
parameter from nvgpu_gmmu_unmap(), as the common case is to store the
address to mem.gpu_va when mapping the buffer.

Modify some instances of consecutive unmap + free calls to call just
nvgpu_dma_unmap_free().
