lttng-modules: Fix "LTTng: vmalloc_sync_all symbol lookup failed" warnings
Fix the following warnings introduced after backporting linux kernel commit [1]
to stable branches:
# lttng create session
...
[ 483.242037] LTTng: vmalloc_sync_all symbol lookup failed.
[ 483.257056] Page fault handler and NMI tracing might trigger faults.
...
These patches should be dropped when a new stable 12.0 release is available.
