The function do_pci_remove() has two local variables 'domid' and
'domainid' containing the same value.

Looking at the history, until 2cf3b50dcd8b ("libxl_pci: Use
libxl__ao_device with pci_remove") the two variables may have
different value when using a stubdomain.

As this is not the case now, remove 'domainid'. This will reduce
the confusion between the two variables.

Note that there are other places in libxl_pci.c which are using
the two confusing names within the same function. They are left
unchanged for now.

No functional changes intented.
