Unionfs: update unionfs_fsync

In v3.16 generic_file_fsync will access ->i_sb->s_bdev->bd_disk, but
s_bdev is NULL for unionfs inode.  This will trigger a kernel panic in
xfstests generic/075, generic/091, etc. as of  kernel v3.16-rc1.

This patch fixes this issue by using __generic_file_fsync, a new
interface introduced in v3.16.
