[PATCH] FIX: Add spare throws exception

sync_metadata() requires st->sb to be loaded, otherwise exception is generated.
This fails expansion, because spares cannot be added.

Patch loads anchor before Manage.c reference to st->sb.

NOTE: This fixes Raid5 expansion, Raid0 expansion is still broken.
