livepatch/core: Fix miss disable ro for MOD_RO_AFTER_INIT memory 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8HNHM

--------------------------------

It was missed to set MOD_RO_AFTER_INIT type memory to be writable
when porting c8783f92 ("livepatch/core: Revert module_enable_ro
and module_disable_ro"). Thanks the report from laokz in
https://gitee.com/laokz/klpmake/issues/I8HFMR

.
