vswitchd: Avoid GCC warning.

GCC 4.4.5 issues the following warning without this patch:

    bridge.c: In function ‘bridge_run’:
    bridge.c:2032: error: ‘database_changed’ may be used uninitialized in
    this function

I think it's unnecessary, but it doesn't hurt to always initialize this
variable.
