msm: kgsl: Fix snapshot dump for hangs involving legacy context switch
The IBs stored by legacy context switch are not stored as part of the
nominal mem_entry accounting that the rest of the process has. As a
result we cannot freeze the legacy context switch IBs for dump. Instead,
dump them into the snapshot as IB sections. Also, store the offset for
the frozen objects to avoid trying to read the gpuaddr of the memdesc after
it had been freed.
