commit 80376323e2b6a4559f86b2b4d864848ac25cb054 upstream. There exist some warnings when building kernel if CONFIG_CPU_HAS_LBT is set but CONFIG_CPU_HAS_LSX and CONFIG_CPU_HAS_LASX are not set. In this case, there are no definitions of _restore_lsx & _restore_lasx and there are also no definitions of kvm_restore_lsx & kvm_restore_lasx in fpu.S and switch.S respectively, just add some ifdefs to fix these warnings.
