powerpc: Remove NULL task struct pointer checks in FP and vector code
We used to allow giveup_*() to be called with a NULL task struct pointer. Now those cases are handled in the caller we can remove the checks. We can also remove giveup_altivec_notask() which is also unused. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
