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.
