[Xen-devel] [PATCH] Initialize ioreq_t in hvmemul_do_io()

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

All relevant fields of the ioreq_t are properly initialized but coverity
complains about vp_eport being uninitialized (ID 1215178) because it is
the subject of a struct copy in hvm_send_assist_req().
