[PATCH] fixup! tlsf: Add tracking of added tlsf memory pools

[Ahmad Fatoum]

tlsf: fix KASAN poisoning of TLSF pool

By poisoning all of the heap after the first malloc, new_pool_entry
becomes a pointer to poisoned memory, which causes a KASAN error right
away at startup.

Move the kasan_poison_shadow call directly after tlsf_add_pool to
fix this.
