Currently, when we call ceph_netfs_issue_read for an encrypted inode,
we'll call iov_iter_get_pages_alloc and assign its result to "err".
Later we'll end up inappropriately calling netfs_subreq_terminated with
that value after submitting the request. Ensure we reset "err = 0;"
after calling iov_iter_get_pages_alloc.

Probably this should get squashed into the patch that adds fscrypt
support to buffered reads.

Looks good. Thanks Jeff!

Show we fold it into the previous patch ?
