GSPRM BUS_GET_PCI_BAR_INFO: reply the canonical 8-entry params struct
The control is cacheable in the guest kernel (RMCTRL_FLAGS_CACHEABLE)
and rmapiControlCacheSet validates paramsSize against the canonical
sizeof(NV2080_CTRL_BUS_GET_PCI_BAR_INFO_PARAMS) = 200. We replied only
8 + 4*24 = 104 bytes, so every reply tripped
NV_ERR_INVALID_PARAMETER in rmapiControlCacheSet (rpc.c:9998) and the
BAR-info cache entry was never populated. Zero-fill and report all
eight NV2080_CTRL_BUS_PCI_BAR_INFO entries (count still 4).
