x86/xsaves: Save xstate to task's xsave area in __save_fpu during booting time

Browse source

__save_fpu() can be called during early booting time when cpu caps are not
enabled and alternative can not be used yet. Therefore, it calls
xsave_state_booting() during booting time to save xstate to task's xsave area.
