Summary
netfs: release readahead folios on iterator preparation failure
Details

In the Linux kernel, the following vulnerability has been resolved:

netfs: release readahead folios on iterator preparation failure

netfspreparereaditerator() batches readahead folios in putbatch so that the folio references can be dropped after the I/O iterator has been prepared.

If rollingbufferloadfromra() fails after earlier folios have been batched, the function returns immediately and leaves those references held. Release the batch before returning the error.
