Remove VMware MSI-X from the PCI blacklist.

Browse Source 
First reported against ESXi 5.0, PCI passthrough was not working due to
MSI-X issues. However, this issue was fixed via patch releases against
ESXi 5.5 and 6.0 in 2016. Given ESXi 5.5 and earlier have been EOL, this
patch removes the VMware MSI-X blacklist entries in the quirk table.
