  Fix a possible NULL pointer dereference in create_cert_store()

In create_cert_store(), X509_STORE_new() is called and there is a
dereference of it in following function X509_STORE_add_lookup()
without check, which could lead to NULL pointer dereference.

Fix this by adding a NULL check of X509_STORE_new()
