MDEV-28049 Error on compiling trx0purge.cc

Browse source 
In commit 83212632e4
the trx_rseg_latch was instrumented for performance_schema,
but some acqusitions of rd_lock() were not adjusted.
Thus, the build would fail on platforms where a futex-based
rw-lock is not available (SUX_LOCK_GENERIC) unless the code
was built with cmake -DPLUGIN_PERFSCHEMA=NO.
