sunrpc: remove redundant variables 'checksumlen','blocksize' and 'data'
Variables 'checksumlen','blocksize' and 'data' are being assigned, but are never used, hence they are redundant and can be removed. Fix the following warning: net/sunrpc/auth_gss/gss_krb5_wrap.c:443:7: warning: variable ‘blocksize’ set but not used [-Wunused-but-set-variable] net/sunrpc/auth_gss/gss_krb5_crypto.c:376:15: warning: variable ‘checksumlen’ set but not used [-Wunused-but-set-variable] net/sunrpc/xprtrdma/svc_rdma.c:97:9: warning: variable ‘data’ set but not used [-Wunused-but-set-variable] Signed-off-by: YueHaibing <yuehaibing@huawei.com> Reviewed-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.
