api: keep AddressSanitizer happy
socket_tx_buffer is a vector, update its length accordingly so that AddressSanitizer can keep track of the allowed memory area. By doing so we can get rid of socket_tx_nbytes which becomes redundant with the vector length. Type: fix Change-Id: Ied7cb430b5dd40d5ed1390aa15bd5f455a0dba62 Signed-off-by: Benoît Ganne <bganne@cisco.com>
