net/smc: add common buffer size in send and receive buffer descriptors

Browse Source 
In addition to the buffer references, SMC currently stores the sizes of
the receive and send buffers in each connection as separate variables.
This patch introduces a buffer length variable in the common buffer
descriptor and uses this length instead.
