LoongArch: KVM: Move LSX capability check in exception handler

Browse Source 
Like FPU exception handler, check LSX capability in the LSX exception
handler rather than function kvm_own_lsx(). Since LSX capability in
the function kvm_guest_has_lsx() implies FPU capability, only checking
kvm_guest_has_lsx() is OK here.
