[PATCH] some vesafb fixes

Browse source 
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.
