x86/fpu: Simplify fpstate_sanitize_xstate() calls

Remove the extra layer of __fpstate_sanitize_xstate():

	if (!use_xsaveopt())
		return;
	__fpstate_sanitize_xstate(tsk);

and move the check for use_xsaveopt() into fpstate_sanitize_xstate().

In general we optimize for the presence of CPU features, not for
the absence of them. Furthermore there's little point in this inlining,
as the call sites are not super hot code paths.

Doing this uninlining shrinks the code a bit:

   text    data     bss     dec     hex filename
   14108751        2573624 1634304 18316679        1177d87 vmlinux.before
   14108627        2573624 1634304 18316555        1177d0b vmlinux.after

Also remove a pointless '!fx' check from fpstate_sanitize_xstate().
