Ed Maste 40efe37e07 Reject invalid CIDR widths rather than silently stopping at the first
non-digit character.

Due to an issue with rc(8) in a test configuration, ifconfig was being
invoked with the address used again as the width - for example,

  ifconfig vlan0 10.0.0.1/10.0.0.1

Prior to this change, that address/width would be interpreted as
10.0.0.1/10.
