Description of problem:
Cannot add vNIC with custom MAC address to VM if there is no addresses left in MAC Address Pool.

Addidng vNIC with _custom_ MAC address should not depend on MAC addresses in pool.

Version-Release number of selected component (if applicable):
Red Hat Enterprise Virtualization Manager Version: 3.3.0-0.38.rc.el6ev 

How reproducible:
100%

Steps to Reproduce:
1. limit MAC address pool to some small amount of MACs
e.g using engine-config --set MacPoolRanges=XX:XX:XX:XX:XX:00-XX:XX:XX:XX:XX:01
2. exhaust MACs by adding vNICs to VM
3. when exhausted, Virtual Machines -> your VM -> Network Intefaces -> New 
4. add meaningful custom MAC e.g. 00:1A:4A:C0:3F:10

Actual results:
Cannot add vNIC with custom MAC address to VM if there is no addresses left in MAC Address Pool.

Expected results:
Addidng vNIC with _custom_ MAC address should not depend on MAC addresses in pool.
