Lee Yarwood 74b053f47a libvirt: Handle VIR_ERR_DEVICE_MISSING when detaching devices
Introduced in libvirt v4.1.0 [1] this error code replaces the previously
raised VIR_ERR_INVALID_ARG, VIR_ERR_OPERATION_FAILED and
VIR_ERR_INVALID_ARG codes [2][3].

VIR_ERR_OPERATION_FAILED was introduced and tested as an
active/live/hot unplug config device detach error code in
I131aaf28d2f5d5d964d4045e3d7d62207079cfb0.

VIR_ERR_INTERNAL_ERROR was introduced and tested as an
active/live/hot unplug config device detach error code in
I3055cd7641de92ab188de73733ca9288a9ca730a.

VIR_ERR_INVALID_ARG was introduced and tested as an
inactive/persistent/cold unplug config device detach error code in
I09230fc47b0950aa5a3db839a070613c9c817576.

This change introduces support for the new VIR_ERR_DEVICE_MISSING error
code while also retaining coverage for these codes until
MIN_LIBVIRT_VERSION is bumped past v4.1.0.

The majority of this change is test code motion with the existing tests
being modified to run against either the active or inactive versions of
the above  error codes for the time being.

test_detach_device_with_retry_operation_internal and
test_detach_device_with_retry_invalid_argument_no_live have been removed
as they duplicate the logic within the now refactored
_test_detach_device_with_retry_second_detach_failure.
