jump_label: skip resource release if jump label is not relocated

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I47NHU


CVE: NA

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

Before a module is deleted, the kernel traverses the jump_label section to
release resources applied by each jump entry. Common modules apply for these
resources before module initialization, but livepatch modules apply during
livepatch redirection.

Therefore, when a livepatch module fails to be inserted, the resources to be
applied by jump_label are not applied. As a result, a panic occurs when a
null pointer is accessed during resource release.

To solve the this problem, skip resource release if jump label is not
relocated.
