video: tegra: host: gk20a: Use NV_KIND_DEFAULT

Currently we do not use kind parameter when mapping buffers, however,
we want to start supporting this. We have used 0 as a dummy parameter
in different places in the driver but 0 is actually a valid data type
and hence it cannot be used for identifying "default type". This
patch modifies the calls to use NV_KIND_DEFAULT in these cases.
