Eric Biggers 6be051ceaf net/tls: use the new scatterwalk functions ...

Replace calls to the deprecated function scatterwalk_copychunks() with
memcpy_from_scatterwalk(), memcpy_to_scatterwalk(), or
scatterwalk_skip() as appropriate.  The new functions generally behave
more as expected and eliminate the need to call scatterwalk_done() or
scatterwalk_pagedone().

However, the new functions intentionally do not advance to the next sg
entry right away, which would have broken chain_to_walk() which is
accessing the fields of struct scatter_walk directly.  To avoid this,
replace chain_to_walk() with scatterwalk_get_sglist() which supports the
needed functionality.
