afs: Translate VNOSERVICE to ETIMEDOUT

Browse Source 
Some fileservers will kill calls that are taking too long with the
VNOSERVICE abort code. Our logic for retrying calls is already aware
of this usage, but if we cannot retry the call, we still just return
VNOSERVICE as an error code to our caller.

Don't return this raw, since has the same value as ENOBUFS, which can
cause a confusing error message from logs or applications ("No buffer
space available"). Return ETIMEDOUT instead.
