[PATCH] arm64/sme: Fix NULL check after kzalloc

[Wan Jiabing]

Fix following coccicheck error:
./arch/arm64/kernel/process.c:322:2-23: alloc with no test, possible model on line 326

Here should be dst->thread.sve_state.

Fixes: 8bd7f91c03d8 ("arm64/sme: Implement traps and syscall handling for SME")
