fs/ntfs3: prevent positive E_NTFS_NONRESIDENT from reaching writeback error handling
attr_data_write_resident() returns the internal positive status code
E_NTFS_NONRESIDENT when the DATA attribute becomes non-resident.
ntfs_writepages() propagates this value into generic writeback error
handling, which expects a standard negative errno and triggers
WARN_ON_ONCE(err > 0).
Translate positive E_NTFS_* status codes to -EIO before recording
the writeback error. This prevents positive internal status codes from
reaching generic writeback code while preserving the existing behaviour
of treating this path as a writeback error.
