qemu.tests.cgroup:modify the way to calculate the cpu counts

Modify code to catch the word 'processor' rather than 'model name'
in /proc/cpuinfo to count cpu number. Becasue the Power cpu haven't
the 'model name' field, and both x86 and Power cpu has the
'processor' field.

qemu.tests.enospc: Fixed 'fuser -k' failed bug

Currently, when running the tests while the clean
up didn't run on the previous, it will raise an
error like:

Test failed: CmdError:
Command <fuser -k /dev/vg_kvm_test_enospc/lv_kvm_test_enospc>
failed, rc=1, Command returned non-zero exit status
[context: performing enospc setup --> performing enospc cleanup]
* Command:
    fuser -k /dev/vg_kvm_test_enospc/lv_kvm_test_enospc
Exit status: 1
Duration: 0.0501132011414

That is the link /dev/vg_kvm_test_enospc/lv_kvm_test_enospc
exist, but no user. thus the command line:
    fuser -k /dev/vg_kvm_test_enospc/lv_kvm_test_enospc
will return 1(fuser will always return none-zero for nobody use).

So just ignore the return status of the fuser.

virt.qemu.tests.nic_bonding:Fix vm.netdev_id error

Nowadays, netdev_id has been a part of nic, and not
belongs to the vm object anymore.

At the sametime nic already has the key 'device_id', so
use nic.device_id is OK.

virt:Make the clock_getres to support POWER guest

The name of the clock on Power guest is "timebase" which is
different from it counterpart in x86 "kvm-clock"

To makes it can work in both Power and x86 guest, add the
platform check.
