CVE-2025-68173

A soft lockup was observed when loading amdgpu module. If a module has a lot of tracable functions, multiple calls to kallsymslookup can spend too much time in RCU critical section and with disabled preemption, causing kernel panic. This is the same issue that was fixed in commit d0b24b4e91fc ("ftrace: Prevent RCU stall on PREEMPTVOLUNTARY kernels") and commit 42ea22e754ba ("ftrace: Add condresched() to ftracegraphsethash()").

Fix it the same way by adding condresched() in ftracemodule_enable.
