On a failure of jent_read_entropy() where the entropy collector will
be reallocated, jent_entropy_collector_free() is used to release
*ec, but *ec is not set to NULL. If a failure occurs in the
following call to jent_entropy_collector_ex() then the function will
return with a dangling pointer remaining in *ec. Set *ec to NULL
after freeing to prevent this.
Upstream PR #97, already merged in master.
