  tls_wolfssl: properly fix crash when clearing the error queue

Make sure the wolfssl error queue is empty after module init so that
multiple processes would not try to free the same elements. Drop the
custom locking callbacks mechanism introduced in commit 0b75867, as each
process allocates it's own queue elements even though shm is used.

Fixes #2667

(cherry picked from commit 91abb6c4fd3851da57c751ac8c97d0757d4b09dc)
