Subject: [patch] some vesafb fixes

Fix the size passed to release_mem_region in an error path.

Also adjust the message printed when vesafb cannot load; the comment
there already says this must not be fatal, so the message should also
not mention the word 'abort' otherwise indicating a problem to worry
about in the log.
