crypto/x509-utils: fix gnutls error code in crt_init failure path

Browse Source 
qcrypto_get_x509_cert_fingerprint() reports gnutls_strerror(ret) when
gnutls_x509_crt_init() fails, but ret is still the initial value -1.
Store the gnutls return code before formatting the error, matching
other gnutls call sites in the tree.
