hw/pci-bridge/cxl_upstream: Fix bandwidth entry base unit for SSLBIS

According to ACPI spec 6.5 5.2.28.4 System Locality Latency and Bandwidth
Information Structure, if the "Entry Base Unit" is 1024 for BW and the
matrix entry has the value of 100, the BW is 100 GB/s. So the
entry_base_unit should be changed from 1000 to 1024 given the comment notes
it's 16GB/s for .latency_bandwidth.

hw/pci-bridge/cxl_upstream.c: Use g_new0() in build_cdat_table()

In build_cdat_table() we do:
*cdat_table = g_malloc0(sizeof(*cdat_table) * CXL_USP_CDAT_NUM_ENTRIES);
This is wrong because:
- cdat_table has type CDATSubHeader ***
- so *cdat_table has type CDATSubHeader **
- so the array we're allocating here should be items of type CDATSubHeader *
- but we pass sizeof(*cdat_table), which is sizeof(CDATSubHeader **),
implying that we're allocating an array of CDATSubHeader **

It happens that sizeof(CDATSubHeader **) == sizeof(CDATSubHeader *)
so nothing blows up, but this should be sizeof(**cdat_table).

Avoid this excessively hard-to-understand code by using
g_new0() instead, which will do the type checking for us.
While we're here, we can drop the useless check against failure,
as g_malloc0() and g_new0() never fail.

This fixes Coverity issue CID 1508120.
