nilfs: fix breakage caused by barrier flag changes

After merging the block tree, today's linux-next build (powerpc ppc64_defconfig)
failed like this:

fs/nilfs2/the_nilfs.c: In function 'nilfs_discard_segments':
fs/nilfs2/the_nilfs.c:673: error: 'DISCARD_FL_BARRIER' undeclared (first use in this function)

Caused by commit fbd9b09a177a481eda256447c881f014f29034fe ("blkdev:
generalize flags for blkdev_issue_fn functions") interacting with commit
e902ec9906e844f4613fa6190c6fa65f162dc86e ("nilfs2: issue discard request
after cleaning segments") (which netered Linus' tree on about March 4 -
before v2.6.34-rc1).
