acrn/dm: Check device file of /dev/acrn_hsm to determine the path of offline VCPU

Browse Source 
For the upstream purpose the device file of /dev/acrn_vhm is renamed
to /dev/acrn_hsm. Correspondingly the path of offline CPU is also changed.
So the device file of /dev/acrn_hsm is checked to configure the path
of ooffline VCPU.
