The tlb shootdown IPI can interrupt the pool_cache_get() in places that
can cause a deadlock or pool cache corruption. Take the shootdown job
queue mutex before calling pool_cache_get(), which will block the IPI
interrupts and seems to fix the remaining tlb shootdown deadlocks and
pool cache corruption I've been seeing. Should address both
PR port-amiga/38335 and PR port-amiga/42174.
