Subject: [PATCH spice 6/6] worker_update_monitors_config: Drop bogus
real_count accounting
1) This does not buy us much, as red_marshall_monitors_config() also
removes 0x0 sized monitors and does a much better job at it
(also removing intermediate ones, not only tailing ones)
2) The code is wrong, as it allocs space for real_count heads, where
real_count always <= monitors_config->count and then stores
monitors_config->count in worker->monitors_config->count, causing
red_marshall_monitors_config to potentially walk
worker->monitors_config->heads past its boundaries.
