netfs: Fix netfs_read_to_pagecache() to pause on subreq failure 

Fix netfs_read_to_pagecache() so that it pauses the generation of new
subrequests if an already-issued subrequest fails.

Fixes: ee4cdf7b ("netfs: Speed up buffered reading")
Closes: https://sashiko.dev/#/patchset/20260425125426.3855807-1-dhowells%40redhat.com
