  ovs-save: Handle MTU changes correctly.

The following command on ubuntu 12.04, 14.04 and CentOS 7.x
returns null:
expr "mtu 1500" : '.*mtu \([0-9]+\)'

But the following works correctly:
expr "mtu 1500" : '.*mtu \([0-9]\+\)'

I am not sure about the portability implications as there
seems to be very sparse documentation about this but
this fixes a bug in 2 of the most popular distributions.
