[PATCH printk v1 1/2] printk: Remove redundant deferred check in vprintk()

[John Ogness <john.ogness@linutronix.de>]

The helper printk_get_console_flush_type() is already calling
is_printk_legacy_deferred() to determine if legacy printing is
to be offloaded. Therefore there is no need for vprintk() to
perform this check as well. Remove the redundant check from
vprintk().
