[PATCH] hw/hyperv/hyperv.c: Use device_cold_reset() instead of device_legacy_reset()

[Peter Maydell]

The semantic difference between the deprecated device_legacy_reset()
function and the newer device_cold_reset() function is that the new
function resets both the device itself and any qbuses it owns,
whereas the legacy function resets just the device itself and nothing
else.  In hyperv_synic_reset() we reset a SynICState, which has no
qbuses, so for this purpose the two functions behave identically and
we can stop using the deprecated one.

NB: tested only with 'make check' and 'make check-avocado', which
may well not exercise this.
