Conor Dooley b8e86aef0a riscv: traps: add missing prototype

commit d951b20b9d upstream.

Sparse complains:
arch/riscv/kernel/traps.c:213:6: warning: symbol 'shadow_stack' was not declared. Should it be static?

The variable is used in entry.S, so declare shadow_stack there
alongside SHADOW_OVERFLOW_STACK_SIZE.

Fixes: 31da94c25a ("riscv: add VMAP_STACK overflow detection")
