misc: fastrpc: fix possible map leak in fastrpc_put_args
commit da1ba64176e0138f2bfa96f9e43e8c3640d01e1e upstream.
copy_to_user() failure would cause an early return without cleaning up
the fdlist, which has been updated by the DSP. This could lead to map
leak. Fix this by redirecting to a cleanup path on failure, ensuring
that all mapped buffers are properly released before returning.
