gpu: nvgpu: Fix logging for pre-4.14 kernels

Browse Source 
It seems that on Tegra kernels older than 4.14 the pre_err() function does
not automatically add a '\n' if you don't supply it.

For older kernels, with the new nvgpu_dbg_dump_impl() function, add this extra
newline so that logs are not hopelessly scrambled.
