[Xen-devel] [PATCH] tools/xenconsoled: Initialise static data before use

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

'fds' and 'current_array_size' are used in a memset() in reset_fds(), and for
the first call to set_fds() before being initialised.

Also initialise nr_fds for sanity sake.

This is another regression introduced by

"Switch from select() to poll() in xenconsoled's IO loop."

This is still not enough to fix the issue of xenconsoled exiting after 384
VMs, but does allow us to reliably reach the 383rd VM.
