Namjae Jeon 523307b851 ntfs: preserve RECALL_ON_OPEN on WSL special-file reparse points
When creating a WSL special file (socket, fifo, character or block
device), __ntfs_create() sets FILE_ATTRIBUTE_RECALL_ON_OPEN in ni->flags
as valid_reparse_data() requires for these tags. This flag is
intentionally absent from $FILE_NAME, so the subsequent reload

        ni->flags = fn->file_attributes;

drops it from ni->flags, the authoritative copy written back to
$STANDARD_INFORMATION. The on-disk file_attributes becomes 0x00000404
instead of 0x00040404, and after a remount valid_reparse_data() rejects
the reparse point while fsck reports "$REPARSE_POINT data is corrupted".

Preserve the RECALL_ON_OPEN bit across the reload. Symlinks do not set
that bit, so they are unaffected.
