esp: fix migration version check in esp_is_version_5()
Commit 4e78f3bf35 "esp: defer command completion interrupt on incoming data transfers" added a version check for use with VMSTATE_*_TEST macros to allow migration from older QEMU versions. Unfortunately the version check fails to work in its current form since if the VMStateDescription version_id is incremented, the test returns false and so the fields are not included in the outgoing migration stream. Change the version check to use >= rather == to ensure that migration works correctly when the ESPState VMStateDescription has version_id > 5.
