nfsd: remove redundant assignment to variable len
[ Upstream commit 842e00ac3aa3b4a4f7f750c8ab54f8578fc875d3 ]
Variable len is being assigned a value zero and this is never
read, it is being re-assigned later. The assignment is redundant
and can be removed.
Cleans up clang scan-build warning:
fs/nfsd/nfsctl.c:636:2: warning: Value stored to 'len' is never read
