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];
^
