GPUParticles3D error spam 'ERROR: Condition "!multimesh" is true.'

Windows 11/64, RTX 3070, Vulkan

Issue description

When emitting, GPUParticles3D spams the console with this:

ERROR: Condition "!multimesh" is true.
   at: _multimesh_get_motion_vectors_offsets (servers/rendering/renderer_rd/storage_rd/mesh_storage.cpp:1291)

It does seem to work, but the error spam really slows down the engine.

Steps to reproduce

• Add a GPUParticles3D node.
• Add any mesh into the drawing pass, either a native one or attach an object.
• System slows down due to error spam.

Whether the mesh has a material, or the emitter has a process material or not makes no difference.
