Although the callers of this function only care about whether the return value is null or not, we should still give a rigorous error code. Smatch tool warning: net/sunrpc/auth_gss/svcauth_gss.c:784 gss_write_verf() warn: returning -1 instead of -ENOMEM is sloppy No functional change, just more standardized.
