MDEV-34204 Assertion `!*detailed_error' failed on shutdown after XA PREPARE

Browse Source 
trx_free_at_shutdown(): Similar to trx_t::commit_in_memory(),
clear the detailed_error (FOREIGN KEY constraint error) before
invoking trx_t::free(). We only do this on debug instrumented
builds in order to avoid a debug assertion failure on shutdown.
