md: raid1: kill warning on powerpc_pseries

This patch kills the warning reported on powerpc_pseries,
and actually we don't need the initialization.

After merging the md tree, today's linux-next build (powerpc
pseries_le_defconfig) produced this warning:

drivers/md/raid1.c: In function 'raid1d':
drivers/md/raid1.c:2172:9: warning: 'page_len$' may be used uninitialized in this function [-Wmaybe-uninitialized]
     if (memcmp(page_address(ppages[j]),
         ^
drivers/md/raid1.c:2160:7: note: 'page_len$' was declared here
   int page_len[RESYNC_PAGES];
       ^
