[PATCH] ring_buffer: Update logging to use single line output

[Joe Perches]

With a possible change to pr_fmt coming, the logging output can
become unbalanced when an initial line has a prefix and subsequent
lines do not when a multiple line pr_<level> is emitted.

Fix it by emitting a single line.

        Miscellanea:

o Convert consecutive tests of total_lost and !total_lost to if/else
