UVD session info size can be upto 128K, we need to allocate a large
enough buffer for the session info, otherwise the IB test can overwrite
other's memory.

Note that the amdgpu_bo functions takes the size in bytes, so this is only 256 bytes (well, probably 4K due to page alignment). I think VCN also needs this fix.
