nfsd: avoid uninitialized variable warning

Browse source

clang warns that 'contextlen' may be accessed without an initialization:

fs/nfsd/nfs4xdr.c:2911:9: error: variable 'contextlen' is uninitialized when used here [-Werror,-Wuninitialized]
                                                                contextlen);
                                                                ^~~~~~~~~~
fs/nfsd/nfs4xdr.c:2424:16: note: initialize the variable 'contextlen' to silence this warning
        int contextlen;
                      ^
                       = 0

Presumably this cannot happen, as FATTR4_WORD2_SECURITY_LABEL is
set if CONFIG_NFSD_V4_SECURITY_LABEL is enabled.
Adding another #ifdef like the other two in this function
avoids the warning.
