x86/idt: Unify gate_struct handling for 32/64-bit kernels
The first 32 bits of gate struct are the same for 32 and 64 bit kernels.
The 32-bit version uses desc_struct and no designated data structure,
so we need different accessors for 32 and 64 bit kernels.
Aside of that the macros which are necessary to build the 32-bit
gate descriptor are horrible to read.
Unify the gate structs and switch all code fiddling with it over.
