nilfs2: replace vmalloc + copy_from_user with vmemdup_user
Replace vmalloc() followed by copy_from_user() with vmemdup_user() to
improve nilfs_ioctl_clean_segments() and nilfs_ioctl_set_suinfo(). Use
kvfree() to free the buffers created by vmemdup_user().
Use u64_to_user_ptr() instead of manually casting the pointers and
remove the obsolete 'out_free' label.
No functional changes intended.
