crypto: Fix certificate file error handling crash bug
qcrypto_tls_creds_load_cert() passes uninitialized GError *gerr by
reference to g_file_get_contents(). When g_file_get_contents() fails,
it'll try to set a GError. Unless @gerr is null by dumb luck, this
logs a ERROR_OVERWRITTEN_WARNING warning message and leaves @gerr
unchanged. qcrypto_tls_creds_load_cert() then dereferences the
uninitialized @gerr.
Fix by initializing @gerr properly.
