[Qemu-devel] [PATCH] block: iscsi build fix if LIBISCSI_FEATURE_IOVECTOR is not defined

[Jeff Cody]

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.
