Documentation: update stale definition of file-nr in fs.txt
In "documentation: update Documentation/filesystem/proc.txt and
Documentation/sysctls" (commit 760df93ec) we merged /proc/sys/fs
documentation in Documentation/sysctl/fs.txt and
Documentation/filesystem/proc.txt, but stale file-nr definition
remained.
This patch adds back the right fs-nr definition for 2.6 kernel.
