David Howells 33b801be2d afs: Fix vlserver probe RTT handling 
[ Upstream commit ba00b19067 ]

In the same spirit as commit ca57f02295 ("afs: Fix fileserver probe
RTT handling"), don't rule out using a vlserver just because there
haven't been enough packets yet to calculate a real rtt.  Always set the
server's probe rtt from the estimate provided by rxrpc_kernel_get_srtt,
which is capped at 1 second.

This could lead to EDESTADDRREQ errors when accessing a cell for the
first time, even though the vl servers are known and have responded to a
probe.

Fixes: 1d4adfaf65 ("rxrpc: Make rxrpc_kernel_get_srtt() indicate validity")
