Su Hui 73424d00dc highmem: fix a memory copy problem in memcpy_from_folio
Clang static checker complains that value stored to 'from' is never read. 
And memcpy_from_folio() only copy the last chunk memory from folio to
destination.  Use 'to += chunk' to replace 'from += chunk' to fix this
typo problem.
