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.
