x86/fpu: Remove failure paths from fpstate-alloc low level functions
Now that we always allocate the FPU context as part of task_struct there's
no need for separate allocations - remove them and their primary failure
handling code.
( Note that there's still secondary error codes that have become superfluous,
those will be removed in separate patches. )
Move the somewhat misplaced setup_xstate_comp() call to the core.
