x86/fpu: Simplify fpstate_init_curr() usage
Now that fpstate_init_curr() is not doing implicit allocations
anymore, almost all uses of it involve a very simple pattern:
if (!fpu->fpstate_active)
fpstate_init_curr(fpu);
which is basically activating the FPU fpstate if it was not active
before.
So propagate the check into the function itself, and rename the
function according to its new purpose:
fpu__activate_curr(fpu);
