firmware/dmi_scan: drop obsolete comment
This comment predates the introduction of early_ioremap. Since then the missing calls to dmi_iounmap have been added by Ingo and Yinghai in commits 0d64484f ("x86: fix DMI ioremap leak") and 3212bff3 ("x86: left over fix for leak of early_ioremp in dmi_scan") . That was over 5 years ago so it is about time to drop this now misleading comment.
