When reading device status, 0 means device is successfully
activated and 1 means error.
This behavior can be observed by the following steps:
1) run a Linux distro on esxi server (5.5+)
2) modify vmxnet3 Linux driver to give it an invalid
address to 'adapter->shared_pa' which is the
shared memory for guest/host communication
This will trigger device activation failure and kernel
log will have the following message:
[ 7138.403256] vmxnet3 0000:03:00.0 eth1: Failed to activate dev: error 1
So return 1 on device activation failure instead of -1;
