David Howells 5c6ce05e40 netfs: Fix barriering when walking subrequest list ...

Fix the barriering used when walking the subrequest list in retry as
there's a possibility of seeing a subreq that's just been added by the
application thread.

Fixes: ee4cdf7ba8 ("netfs: Speed up buffered reading")
Fixes: 288ace2f57 ("netfs: New writeback implementation")
