[libvirt] [PATCH 2/3] rpc: avoid uninitialized memory use

[Eric Blake]

Spotted by Coverity.  Gnutls documents that buffer must be NULL
if gnutls_x509_crt_get_key_purpose_oid is to be used to determine
the correct size needed for allocating a buffer.

* src/rpc/virnettlscontext.c
(virNetTLSContextCheckCertKeyPurpose): Initialize buffer.
