[PATCH 1/2] ntfs: apply Windows name checks only with windows_names

The windows_names mount option is documented to reject names containing
characters forbidden by Windows. However, ntfs_check_bad_windows_name()
unconditionally rejects those characters before checking the mount option.

Move the character validation after the option check so a default NTFS
mount accepts POSIX names such as names containing ':'. Mounts using
windows_names retain the existing Windows-compatible validation, including
reserved device names and trailing spaces or dots.
