arch_topology: Fix missing clear cluster_cpumask in remove_cpu_topology()

When testing cpu online and offline, warning happened like this:

For some architectures like risc-v and arm64 which use common code
clear_cpu_topology() in shutting down CPUx, When CONFIG_SCHED_CLUSTER
is set, cluster_sibling in cpu_topology of each sibling adjacent
to CPUx is missed clearing, this causes checking failed in
topology_span_sane() and rebuilding topology failure at end when CPU online.

Different sibling's cluster_sibling in cpu_topology[] when CPU92 offline
(CPU 92, 93, 94, 95 are in one cluster):

Before revision:
CPU                 [92]      [93]      [94]      [95]
cluster_sibling     [92]     [92-95]   [92-95]   [92-95]

After revision:
CPU                 [92]      [93]      [94]      [95]
cluster_sibling     [92]     [93-95]   [93-95]   [93-95]
