MDEV-30900 Crash on macOS due to zero-initialized buf_dblwr.write_cond

Browse source 
buf_dblwr_t::init(), buf_dblwr_t::close(): Cover also write_cond,
which was added in commit a55b951e60
without explicit initialization. On GNU/Linux, PTHREAD_COND_INITIALIZER
is a zero-initializer. That is why the default zero initialization
happened to work on that platform.
