printk: add pr_flush()
Provide a might-sleep function to allow waiting for console printers
to catch up to the latest logged message.
Use pr_flush() whenever it is desirable to get buffered messages
printed before continuing: suspend_console(), resume_console(),
console_stop(), console_start(), console_unblank().
