Subject[PATCH 2/2] nfsd: fix compile warning about unused variable 'nn'
Date
Commit c9a4962881 (nfsd: make client_lock per net) added
lockdep_assert_held() call to function free_client(). However, if lockdep
is disabled we get following compiler warning:

fs/nfsd/nfs4state.c: In function ‘free_client’:
fs/nfsd/nfs4state.c:1051:19: warning: unused variable ‘nn’ [-Wunused-variable]

Fix this by marking the 'nn' with __maybe_unused.
