[OpenAFS] Minor remark, inappropiate error message

[RL]

A minor remark :

( strings /usr/vice/etc/afsd | grep OpenAFS :
    @(#)OpenAFS 1.8.7 2021-01-17 admin@hal.localdomain
)

fs sp -vl achan.server.rpi.edu      10000 :
  achan.server.rpi.edu: couldn't resolve name.
  This cache manager does not support VL server preferences

  ^--- This is a misleading message ------------------------------- <<<<<
   really, it does support preferences for *resolved* names

Best regards
Rainer
