[PATCH 1/3] printk/console: Remove superfluous setting of has_preferred state value

[Petr Mladek]

It is superfluous to set "has_preferred" when the really preferred
console is enabled. The variable "i" is index of an array. Therefore
"has_preferred" is set only when preferred_console is >= 0. But then
it was already true because of the above code:

        if (!has_preferred || bcon || !console_drivers)
                has_preferred = preferred_console >= 0;

This line was added by the commit ab4af03a4054bd78bc ("[PATCH] CON_CONSDEV
bit not set correctly on last console"). It was kind of logic to store
the really used index there. But this commit actually caused that
"preferred_console" started to be used only as a boolean. This was
discovered and corrected by the commit b077bafa2f3848ddfcef ("printk:
fix name/type/scope of preferred_console var").
