lib/stacktrace: drop impossible WARN_ON for depot_init_pool
depot_init_pool has two call sites:
1. In depot_alloc_stack with a potentially NULL prealloc.
2. In __stack_depot_save with a non-NULL prealloc.
At the same time depot_init_pool can only return false when prealloc is
NULL.
As the second call site makes sure that prealloc is not NULL, the WARN_ON
there can never trigger. Thus, drop the WARN_ON and also move the prealloc
check from depot_init_pool to its first call site.
Also change the return type of depot_init_pool to void as it now always
returns true.
