md/md-cluster: fix spares warnings for __le64
[ Upstream commit 82697ccf7e495c1ba81e315c2886d6220ff84c2c ]
drivers/md/md-cluster.c:1220:22: warning: incorrect type in assignment (different base types)
drivers/md/md-cluster.c:1220:22: expected unsigned long my_sync_size
drivers/md/md-cluster.c:1220:22: got restricted __le64 [usertype] sync_size
drivers/md/md-cluster.c:1252:35: warning: incorrect type in assignment (different base types)
drivers/md/md-cluster.c:1252:35: expected unsigned long sync_size
drivers/md/md-cluster.c:1252:35: got restricted __le64 [usertype] sync_size
drivers/md/md-cluster.c:1253:41: warning: restricted __le64 degrades to integer
Fix the warnings by using le64_to_cpu() to convet __le64 to integer.
