    sys/vfs/tmpfs: Make flag handling consistent [1/2]
    
    - Not taking inode lock on if-test for inode status introduces
      a potential race.
    
    - Above race is basically harmless though since if-test itself
      was redundant and basically results the same with or without it.
      So get rid of it and keep the |= part with inode lock.
