* CLI: Fix long delay with quick connect/disconnect noticeable with qflipper, for some reason it sets DTR on/off/on again so flipper starts CLI, stops it, then starts again but cli shell is trying to print motd, and pipe is already broken so each character of motd times out for 100ms changing pipe timeout to 10ms works too, but is just a workaround it didnt always happen, i think that variable time of loading ext cmds made it so on ofw it usually manages to print motd before pipe is broken on cfw with more ext commands it always hung, on ofw only sometimes important part is bailing early in cli shell in cli vcp i made it cleanup cli shell on disconnect so it doesnt stay around after disconnecting usb, might free a little ram maybe * cli_shell: possibly more robust fix? * Fix use after free crash * cli_shell: waste even less time Co-Authored-By: WillyJL <me@willyjl.dev> --------- Co-authored-by: Anna Antonenko <portasynthinca3@gmail.com> Co-authored-by: hedger <hedger@users.noreply.github.com>
