sysfs: Pack sysfs_dirent more tightly.
Placing the 16bit s_mode between a pointer and a long doesn't pack well especailly on 64bit where we wast 48 bits. So move s_mode and declare it as a unsigned short. This is the sysfs backing store after all we don't need fields extra large just in case someday we want userspace to be able to use a larger value.
