Annotate geom modules with MODULE_VERSION
GEOM ELI may double ask the password during boot. Once at loader time, and once at init time. This happens due a module loading bug. By default GEOM ELI caches the password in the kernel, but without the MODULE_VERSION annotation, the kernel loads over the kernel module, even if the GEOM ELI was compiled into the kernel. In this case, the newly loaded module purges/invalidates/overwrites the GEOM ELI's password cache, which causes the double asking. MFC Note: There's a pc98 component to the original submission that is omitted here due to pc98 removal in head. This part will need to be revived upon MFC.
