Updated VMWARE_BALLOON_CMD to use the common VMW_PORT macro.
Doing this rather than replacing all instances of VMWARE_BALLOON_CMD
to minimize code change.

v1
Swapped parameters 1 and 2 to VMW_PORT because the macro has been
updated
v2
Updated VMW_PORT() usage because the macro and vmw_balloon.c's
usage have changed.
