removing assertion (will be moved to 4.1) for non-debug to compile

Browse source 
sql/sql_class.h:
  removing the assertion as I don't want to include assert.h (inclusion of assert.h has already been
  reworked in 4.1, so I'll move the assertion to 4.1). Assertion makes compilation fail if non-debug.

/*
For enter_cond() / exit_cond() to work the mutex must be got before
enter_cond() but released before exit_cond() (in 4.1, assertions will soon
ensure this). Use must be:
lock mutex; enter_cond(); ...; unlock mutex; exit_cond().
If you don't do it this way, you will get a deadlock if another thread is
doing a THD::awake() on you.
