[PATCH 5/9] bfs: move function prototype to the proper header file

[Dmitri Vorobiev]

The dump_imap() routine is defined in bs/bfs/inode.c and used both in
the same file and in fs/bfs/dir.c. This patch adds an extern function
declaration to the private bfs.h header file.

The effect is that one warning issued by checkpatch.pl is gone.

Before the patch:

$ ./scripts/checkpatch.pl --file  fs/bfs/dir.c | grep total
total: 0 errors, 1 warnings, 370 lines checked

After the patch:

$ ./scripts/checkpatch.pl --file  fs/bfs/dir.c | grep total
total: 0 errors, 0 warnings, 368 lines checked

This patch was compile-tested by building the BFS driver both
as a module and as a part of the kernel proper.
