drm/amdgpu/userqueue: Fix use after free in amdgpu_userq_buffer_vas_list_cleanup()

The amdgpu_userq_buffer_va_list_del() function frees "va_cursor" but it
is dereferenced on the next line when we print the debug message.  Print
the debug message first and then free it.

Fixes: 2a28f9665dca ("drm/amdgpu: track the userq bo va for its obj management")
