Commit b03c380 introduced the function
iscsi_allocationmap_is_allocated(), however it is only used within a
code block that is conditionally compiled.  This produces a warning
(error with -werror) of "defined but not used" for the the function, if
LIBISCSI_FEATURE_IOVECTOR is not defined.

This wraps iscsi_allocationmap_is_allocated() in the same conditional.

The new #endif and the subsequent #if can be elided.

Applied to scsi-next with this change, thanks.
