[patch 099/108] mm/zswap.c: improve a size determination in zswap_frontswap_init()

[akpm]

From: Markus Elfring <elfring@users.sourceforge.net>
Subject: mm/zswap.c: improve a size determination in zswap_frontswap_init()

Replace the specification of a data structure by a pointer dereference as
the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
