ima: fallback to MODULE_SIG_ENFORCE for existing kernel module syscall
The new kernel module syscall appraises kernel modules based
on policy. If the IMA policy requires kernel module checking,
fallback to module signature enforcing for the existing syscall.
Without CONFIG_MODULE_SIG_FORCE enabled, the kernel module's
integrity is unknown, return -EACCES.
Changelog v1:
- Fix ima_module_check() return result (Tetsuo Handa)
