Konsta Holtta 2119213467 gpu: nvgpu: use NO_KERNEL_MAPPING for default vidmem ...

Commit 8f3875393e ("abstract away dma
alloc attrs") added an implicit NVGPU_DMA_NO_KERNEL_MAPPING for the
explicit vidmem buffer allocation path. The default allocation api that
chooses vidmem or sysmem based on available support still passed a zero
flag and produced a warning when the flag should have been there. Force
the NO_KERNEL_MAPPING flag on currently via the default-allocator api.

Commit 8a15e02ca9 ("gpu: nvgpu: add
NO_KERNEL_MAPPING for alloc_map_vid") did the same for flagless
alloc-and-map calls but this default alloc-only call got overlooked.

Also, store the flags in the mem_desc during allocation, just like in
the sysmem allocator, to be checked during freeing.
