Fix a possible memleak in bind_afalg
bind_afalg calls afalg_aes_cbc which allocates cipher_handle->_hidden global object(s) but if one of them fails due to out of memory, the function bind_afalg relies on the engine destroy method to be called. But that does not happen because the dynamic engine object is not destroyed in the usual way in dynamic_load in this case: If the bind_engine function fails, there will be no further calls into the shared object.
