Vincent Chen aaaaba5750 nds32: Disable local irq before calling cpu_dcache_wb_page in copy_user_highpage 
In order to ensure that all data in source page has been written back
to memory before copy_page, the local irq shall be disabled before
calling cpu_dcache_wb_page(). In addition, removing unneeded page
invalidation for 'to' page.
