Subject: [PATCH] lib/scatterlist: fix kerneldoc for sg_pcopy_{to,from}_buffer()

The kerneldoc for the functions doesn't match the code; the
last two parameters (buflen, skip) have been transposed, which
is confusing, especially as they're both integral types and the
compiler won't warn about swapping them.

These functions and the kerneldoc were introduced in commit:
    df642cea lib/scatterlist: introduce sg_pcopy_from_buffer() ...
    Author: Akinobu Mita <akinobu.mita@...il.com>
    Date:   Mon Jul 8 16:01:54 2013 -0700

    The only difference between sg_pcopy_{from,to}_buffer() and
    sg_copy_{from,to}_buffer() is an additional argument that
    specifies the number of bytes to skip the SG list before
    copying.

The functions have the extra argument at the end, but the kerneldoc
lists it in penultimate position.
