readline: don't free completions in readline_free()
Since commit e5dc1a6c6c43, QEMU aborts on exit if completion was used
in the monitor:
*** Error in `obj/ppc64-softmmu/qemu-system-ppc64': double free or
corruption (fasttop): 0x00000100331069d0 ***
/home/greg/Work/qemu/qemu-spapr/util/readline.c:514
/home/greg/Work/qemu/qemu-spapr/monitor.c:586
/home/greg/Work/qemu/qemu-spapr/monitor.c:4125
argv=<optimized out>, envp=<optimized out>) at
/home/greg/Work/qemu/qemu-spapr/vl.c:4795
Completion strings are not persistent accross completions (why would
they?). They are allocated under readline_completion(), which already
takes care of freeing them before returning.
Maybe all completion related bits should be moved out of ReadLineState
to a dedicated structure ?
In the meantime, let's drop the offending lines from readline_free()
to fix the crash.
