[ARM/Tegra] nvrm : Clean up user mode DMA handles
Nvrm exposes nvrm DMA APIs to allocate and use the DMA channel
from user mode. I2S (i.e audio HAL) is the main user of these
APIs. When the process that allocates the handles doesn't free-up
and crashes, RM reftracker driver will clean up the handles its
on-behalf. Same mechanism already exists for the mmeory handles.
