fuse: fix nlink after unlink
Anand Avati reports that the following sequence of system calls fail on a fuse
filesystem:
create("filename") => 0
link("filename", "linkname") => 0
unlink("filename") => 0
link("linkname", "filename") => -ENOENT ### BUG ###
vfs_link() fails with ENOENT if i_nlink is zero, this is done to prevent
resurrecting already deleted files.
Fuse clears i_nlink on unlink even if there are other links pointing to the
file.
