riscv: Remove SHADOW_OVERFLOW_STACK_SIZE macro 

[ Upstream commit a7565f4d068b2e60f95c3223c3167c40b8fe83ae ]

The commit be97d0db5f44 ("riscv: VMAP_STACK overflow
detection thread-safe") got rid of `shadow_stack`,
so SHADOW_OVERFLOW_STACK_SIZE should be removed too.

Fixes: be97d0db5f44 ("riscv: VMAP_STACK overflow detection thread-safe")
