vlib: use error description when dropping packets

Using the error name makes it less explicit in the packet trace than
the error description when a packet is dropped. Example of the trace
when the TTL is <=1:

01:03:17:015278: drop
  ip4-input: time_expired

We should have "ip4 ttl <= 1" instead of "time_expired"
