xen: fix multicall debug feature
Initializing a percpu variable with the address of a struct tagged as
.initdata is breaking the build with CONFIG_SECTION_MISMATCH_WARN_ONLY
not set to "y".
Fix that by using an access function instead returning the .initdata
struct address if the percpu space of the struct hasn't been
allocated yet.
