gpu: nvgpu: use NO_KERNEL_MAPPING for default vidmem
Commit 8f3875393e7a6bd0fc03afdb1fa99b7e33b71576 ("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 8a15e02ca92b83aa5a216ea9cd42680373212ecd ("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.
