commit 2621a102cd74cd6691bed30f638581639fcb141d

passthrough: Fix MSI-x devices assignment.

Currenlty, assigned MSI-x devices fails to
work due to incorrect table_offset_adjust setting.
The last field msix_entryof struct pt_msix_info is
a variable-size array, so there shouldn't be any field
after it, otherwise they maybe destroyed
when access msix_entry.
