kfence: Defer the assignment of the local variable addr
The LoongArch architecture is different from other architectures. It
needs to update __kfence_pool during arch_kfence_init_pool().
This patch modifies the assignment location of the local variable addr
in the kfence_init_pool() function to support the case of updating
__kfence_pool in arch_kfence_init_pool().
