Set is_head in extent_alloc_wrapper w/ retain.

Browse Source 
When retain is on, when extent_grow_retained failed (e.g. due to split hook
failures), we'll try extent_alloc_wrapper as the last resort.  Set the is_head
bit in that case to be consistent.  The allocated extent in that case will be
retained properly, but not merged with other extents.
