Subject: libconsole: Really allow to use /dev/console as a fallback in showconsole
Git-commit: 19329e59e442c81d270028cbc945fe83a9732327
References: bsc#1071568
Upstream: merged

consalloc() always returns an error when it is called from
showconsole (with io = 0). As a result, /dev/console is ignored
because it is not assigned to the global "cons" pointer
in getconsoles().

consalloc() should return success (1) when the console is added
to the list and the io-related operations are skipped.
