write_entry: fix leak when retrying delayed filter

When write_entry() retries a delayed filter request, we
don't need to send the blob content to the filter again, and
set the pointer to NULL. But doing so means we leak the
contents we read earlier from read_blob_entry(). Let's make
sure to free it before dropping the pointer.
