Under race conditions it is possible that there is no call

ull_disable function checks for reference count before
using a mayfly to schedule lll_disable, which in turn
would close requested currently active role event leading
to done event being propogated to ULL. Done event would
then call the set disabled_cb callback when the reference
count is zero, giving the semaphore to the waiting
k_sem_give in the ull_disable.
Under race conditions if the reference count reached zero
after the reference count check and before the disabled_cb
was assigned in the ull_disable function, then there are
chances that a k_sem_give is not called while ull_disable
