fs/Kconfig: move nilfs2 out
fs/Kconfig file was split into individual fs/*/Kconfig files before
nilfs was merged. I've found the current config entry of nilfs is
tainting the work. Sorry, I didn't notice. This fixes the violation.

6 | NILFS2 is a log-structured file system (LFS) supporting continuous | ||
7 | snapshotting. In addition to versioning capability of the entire | ||
8 | file system, users can even restore files mistakenly overwritten or | ||
9 | destroyed just a few seconds ago. Since this file system can keep | ||
10 | consistency like conventional LFS, it achieves quick recovery after | ||
11 | system crashes. | ||
12 | |||
13 | NILFS2 creates a number of checkpoints every few seconds or per | ||
14 | synchronous write basis (unless there is no change). Users can | ||
15 | select significant versions among continuously created checkpoints, | ||
16 | and can change them into snapshots which will be preserved for long | ||
17 | periods until they are changed back to checkpoints. Each | ||
18 | snapshot is mountable as a read-only file system concurrently with | ||
19 | its writable mount, and this feature is convenient for online backup. | ||
20 | |||
21 | Some features including atime, extended attributes, and POSIX ACLs, | ||
22 | are not supported yet. | ||
23 | |||
24 | To compile this file system support as a module, choose M here: the | ||
25 | module will be called nilfs2. If unsure, say N. | ||
