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.

Eh, I'm not sure I understand why this is important but, OK,
