I didn't get any warning with CONFIG_SYSCTL=n.

Okay, it seems reasonable. We can simply remove 'server'. Please
consider the following patch (also attached, might have some white
space issue).

When CONFIG_NFS=y and CONFIG_NFS_V3_{,V4}=n we get the following warning.
fs/nfs/write.c: In function ‘nfs_writeback_done’:
fs/nfs/write.c:1246:21: warning: unused variable ‘server’
Remove the variable 'server' to fix the above warning.
