Otherwise, the gdb connection can be abruptly disconnected resulting in the last gdb packet "Wxx" being not sent. For the gdbstub modification, gdb_exit calls ensure that the "Wxx" packet is sent before exiting. However, some features (see net/vhost-vdpa.c: vhost_vdpa_cleanup for example) are expecting that a cleanup is being made before exiting. This, it's probably safer to follow the same logic here as well.
