netfs: Fix read-retry for fs with no ->prepare_read() 
Fix netfslib's read-retry to only call ->prepare_read() in the backing
filesystem such a function is provided.  We can get to this point if a
there's an active cache as failed reads from the cache need negotiating
with the server instead.

Fixes: ee4cdf7ba8 ("netfs: Speed up buffered reading")
