[PATCH] qemu: Resolve Coverity DEADCODE

[John Ferlan <jferlan@xxxxxxxxxx>]

Coverity notes taht the switch() used to check 'connected' values has
two DEADCODE paths (_DEFAULT & _LAST).  Since 'connected' is a boolean
it can only be one or the other (CONNECTED or DISCONNECTED), so it just
seems pointless to use a switch to get "all" values.  Convert to if-else
