Lin Ma 9e14037f05 msmouse: Fix segfault caused by free the chr before chardev cleanup. ...

The chr was freed by msmouse close callback before chardev cleanup, Then qemu_mutex_destroy triggered raise(). Because freeing chr is handled by qemu_chr_free_common, Remove the free from msmouse_chr_close to avoid double free.
