Hoist the "master vs apprentice" label to apprentice(), since
we will want different labels for dumping. Remove all of the
"mismatch" text from reginfo_dump_mismatch -- just print "vs".

Since this is only risu, not QEMU proper, I don't think we strictly need to disentangle this into two commits, but we should describe both changes in the commit message. (Since the only callsite doesn't check the return value and in any case if it cared it could call ferror() itself, switching to 'void' is fine.) thanks -- PMM
