Fixing a crash after applying the wrong TLS configuration.

When an invalid TLS configuration is applied (such as the conf_commands
feature), nxt_cert_store_get() creates a buffer to send a certificate request
to the main process and adds its default completion handler to an asynchronous
queue to free the allocated buffer.  However, if configuration fails,
nxt_router_conf_error() removes the memory pool used to allocate the buffer,
causing a crash when the completion handler is dispatched.


Assertion "src/nxt_buf.c:208 assertion failed: data == b->parent" is triggered
when is NXT_DEBUG enabled in the configure script.


This patch uses a reference counter to retain the memory pool and redefines the
completion handler to free the buffer before releasing the memory pool.
