zsmalloc: set default zspage chain size to 8 

JIRA: https://issues.redhat.com/browse/RHEL-27740
Tested: by me

commit b46402fa894f88ddb42a2e841618a8f42f57d16d

    zsmalloc: set default zspage chain size to 8

    This changes key characteristics (pages per-zspage and objects per-zspage)
    of a number of size classes which in results in different pool
    configuration.  With zspage chain size of 8 we have more size clases
    clusters (123) and higher huge size class watermark (3632 bytes).

    Please read zsmalloc documentation for more details.
