fix handling of PORT_PROFILE_RESPONSE_INPROGRESS netlink message

During function test of the 802.1Qbg implementation in lldpad we came
across a small problem in the handling of the netlink message
corresponding to PORT_PROFILE_RESPONSE_INPROGRESS. This should not
result in returning the default rc=1.

- src/util/macvtap.c: fix getPortProfileStatus() to return 0 in that
  case and also fix an indentation problem
