x86/process: Define cpu_tss_rw in same section as declaration

cpu_tss_rw is declared with DECLARE_PER_CPU_PAGE_ALIGNED
but then defined with DEFINE_PER_CPU_SHARED_ALIGNED
leading to section mismatch warnings.

Use DEFINE_PER_CPU_PAGE_ALIGNED consistently. This is necessary because
it's mapped to the cpu entry area and must be page aligned.

[ tglx: Massaged changelog a bit ]
