    xen/grant-table: Remove outdated warning in gnttab_grow_table()
    
    One of the warning message in gnttab_grow_table() refers to a function
    was removed in commit 6425f91c72 "xen/gnttab: Fold grant_table_{create,
    set_limits}() into grant_table_init()".
    
    Since the commit, gt->active will be allocated while initializing the
    grant table at domain creation. Therefore gt-active will always be
    valid.
    
    Rather than replacing the warning by another one, drop the check
    completely as we will likely not come back to a semi-initialized world.
