[Qemu-devel] [PULL v1 2/3] crypto: fix building complaint

[Daniel P. Berrange]

From: Gonglei <address@hidden>

gnutls commit 846753877d renamed LIBGNUTLS_VERSION_NUMBER to 
GNUTLS_VERSION_NUMBER.
If using gnutls before that verion, we'll get the below warning:
crypto/tlscredsx509.c:618:5: warning: "GNUTLS_VERSION_NUMBER" is not defined

Because gnutls 3.x still defines LIBGNUTLS_VERSION_NUMBER for back compat, Let's
use LIBGNUTLS_VERSION_NUMBER instead of GNUTLS_VERSION_NUMBER to fix building
complaint.
