[Ben Hutchings]

------------------

From: Daniel Jordan <daniel.m.jordan@xxxxxxxxxx>

commit 955c97f0859abef698e77f5697f5c4008303abb9 upstream.

Commit 570a335b8e22 ("swap_info: swap count continuations") introduces
COUNT_CONTINUED but refers to it incorrectly as SWAP_HAS_CONT in a
comment in swap_count.  Fix it.
