Describe the Bug

Regardless of whether the cold read control switch is turned on, initPageSize() will be executed. However in some cases it may trigger an error.

Steps to Reproduce

turn off the related switch:
coldDataScanEnable = false
coldDataFlowControlEnable = false

then start the broker, there will still be such log in store.log:
2023-07-03 13:54:01 INFO main - initPageSize pageSize: 4096

However, this discussion shows that in some cases, it will lead to an error:
#7007

What Did You Expect to See?

The initialization should only be triggered after the switch is turned on.

What Did You See Instead?

then start the broker, there is such log in store.log:
2023-07-03 13:54:01 INFO main - initPageSize pageSize: 4096
