URL: https://github.com/apache/nuttx/pull/21268
## Summary
tcp_selectport() unconditionally called NET_PORT_RANDOM_INIT()
(arc4random_buf -> getrandom -> open("/dev/urandom")) even for fixed-port
binds, which can overflow small stacks. Random port init is only needed for the
portno == 0 (auto-assign) path.
