debugobjects: Use LD_WAIT_CONFIG instead of LD_WAIT_SLEEP

fill_pool_map is used to suppress nesting violations caused by acquiring
a spinlock_t (from within the memory allocator) while holding a
raw_spinlock_t. The used annotation is wrong.

LD_WAIT_SLEEP is for always sleeping lock types such as mutex_t.
LD_WAIT_CONFIG is for lock type which are sleeping while spinning on
PREEMPT_RT such as spinlock_t.

Use LD_WAIT_CONFIG as override.
