Subject: [PATCH] Mark SSL ctx unused in ssl_prepare_reassembly_buffer() if
 !DEBUG

The SSL context is passed to the reassembly preparation function
ssl_prepare_reassembly_buffer() solely for the purpose of allowing
debugging output. This commit marks the context as unused if
debugging is disabled (through !MBEDTLS_DEBUG_C).
