[libc] remove rtlibc[Netif] Fix the eth_tx_msg protection2021-09-11T05:11:57ZGrissiomgrissiom@163.com2021-09-11T05:11:57Zurn:sha1:1ebf7b5196b069c9efefe558d5b5abf492244511
The ethernetif use semaphore netif->tx_ack to protect the local variable
`struct eth_tx_msg msg` in function `ethernetif_linkoutput`. But the
function could be called in multiple context: LwIP "tcpip" thread, "erx"
thread(on linkup) and any user thread that call `udp_sendto`. So the
global semaphore protection is not sufficient. It could only wakeup the
top priority waiting thread instead of the thread that owns the `msg`
and may result the `msg` next in the mailbox got destructed.
So to use a `rt_completion` within the `struct eth_tx_msg` and
synchronize on that. This could deal the ownership issue in an easy way.

1、更正lwip_accept()中调用netconn_peer()失败时，netconn_delete()会被调用两次，从而导致进入rt_assert_handler()错误。
