ethtool: fix wrong assignment for global variable

In python, variables that are only referenced inside a function
are implicitly global. And if a variable is assigned a new value
anywhere within the function's body, it's assumed to be a local.

so ethtool_save_params() doesn't truely store the ethtool status
into global variable 'pretest_status'. we can simply make use of
by 'global' to fix the problem, but it's not a good method.

The usb_storage tests report couple of errors, says:
* missing blk_extra_params_stg
* Expected: '520fa169-32f8-431f-9f1e-70992671d2e5', Actual: 'TARGET_DISK0'
('520fa169-..' is generated dynamically, 'TARGET_..' is my blk_extra_params_stg)

This patch fixes above issues.

To avoid the packet lose, need to make sure the vcpus + vhosts <= pcpus
and pin vcpus/vhosts into different cpu.
