Only a tiny modification in patch "megasas: remove unnecessary
megasas_use_msix()" to fix a megasas issue.

v8 changelog:
1. reorder: place the "megasas: remove unnecessary megasas_use_msix()"
   as the last one. and fix the bug in it, detailed description in it,
   also removed the R-b of it.
2. Add the Acked-by from Marcel for first 9 patches; add the R-b from Markus
   to "hcd-xhci: check & correct param before using it".

1. make check ok
2. command line test for all affected device, make sure their realization
   is ok.
3. detailed test for megasas, hcd-xhci, vmxnet3.
   megasas: install a linux distro is ok
   ./qemu-system-x86_64 --enable-kvm -m 1024
   -device megasas,id=scsi0,bus=pci.0
   -drive file=/xx/scsi-disk.img,if=none,id=drive-scsi0
   -cdrom /xx/Fedora-Server-DVD-x86_64-23.iso --monitor stdio

   hcd-xhci: partition the usbstick.img, mkfs, write to file, is ok
   ./qemu-system-x86_64 -M q35 -m 1024 --enable-kvm
   -drive if=none,id=usbstick,file=/xx/usbstick.img
   -device nec-usb-xhci,id=usb,p2=8,p3=8,bus=pcie.0
   -device usb-storage,bus=usb.0,drive=usbstick --monitor stdio

   vmxnet3: ping another destination belongs to host's network is ok.
   But no migration test, because I don't have a spare machine for now.
   ./qemu-system-x86_64 -M q35 -m 1024 --enable-kvm
   -netdev tap,id=mynet0 -device vmxnet3,netdev=mynet0
   --monitor stdio /home/pino/vm/FedoraWorkStatsion23-x86_64.img
