[PATCH 5/9] NFS: Squelch compiler warning in nfs_add_server_stats()

[Chuck Lever <chuck.lever@oracle.com>]

Clean up:

fs/nfs/iostat.h: In function =E2=80=98nfs_add_server_stats=E2=80=99:
fs/nfs/iostat.h:41: warning: comparison between signed and unsigned int=
eger expressions
fs/nfs/iostat.h:41: warning: comparison between signed and unsigned int=
eger expressions
fs/nfs/iostat.h:41: warning: comparison between signed and unsigned int=
eger expressions
fs/nfs/iostat.h:41: warning: comparison between signed and unsigned int=
eger expressions

Commit fce22848 replaced the open-coded per-cpu logic in several
functions in fs/nfs/iostat.h with a single invocation of
this_cpu_ptr().  This macro assumes its second argument is signed,
not unsigned.
