Kernel test robot throws below warning -

>> fs/nfsd/nfs3xdr.c:299:6: warning: variable 'err' is used
>> uninitialized whenever 'if' condition is false
>> [-Wsometimes-uninitialized]
           if (!v4 || !inode->i_sb->s_export_op->fetch_iversion)
               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   fs/nfsd/nfs3xdr.c:304:6: note: uninitialized use occurs here
           if (err) {
               ^~~
   fs/nfsd/nfs3xdr.c:299:2: note: remove the 'if' if its condition is
always true
           if (!v4 || !inode->i_sb->s_export_op->fetch_iversion)
           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   fs/nfsd/nfs3xdr.c:293:12: note: initialize the variable 'err' to
silence this warning
           __be32 err;
                     ^
