x86/ldt: Make all size computations unsigned
ldt->size can never be negative. The helper functions take 'unsigned int' arguments which are assigned from ldt->size. The related user space user_desc struct member entry_number is unsigned as well. But ldt->size itself and a few local variables which are related to ldt->size are type 'int' which makes no sense whatsoever and results in typecasts which make the eyes bleed. Clean it up and convert everything which is related to ldt->size to unsigned it.
