URL: https://github.com/apache/nuttx/pull/20446

   ## Summary
   
   SMARTFS_DIRENT_RESERVED uses bits that overlap S_ISUID, S_ISGID, and 
S_ISVTX. smartfs_stat_common() currently clears only S_IFMT, allowing reserved 
directory-entry flags to appear in st_mode and ls output as setuid and setgid 
bits. Preserve only SMARTFS_DIRENT_MODE when constructing st_mode.
   
   ## Impact
   
   - Fixes incorrect SmartFS `stat()` and `ls -l` mode reporting.
   - Prevents reserved SmartFS metadata bits from appearing as setuid/setgid 
bits.
   - No on-disk format, API, or filesystem compatibility changes.
   
   ## Testing
   
   ```
   mount -t smartfs /dev/smart0 /mnt
   ls -l /mnt
   -rw-rw-rw-          13 testfile
   ```
