thread.c (rb_reset_coverages): remove coverage counters from all ISeqs
When coverage measurement is enabled, the compiler makes each iseq have
a reference to the counter array of coverage.
Even after coverage measurement is disabled, the reference is kept.
And, if coverage measurement is restarted, a coverage hook will increase
the counter. This is completely meaningless; it brings just overhead.
To remove this meaninglessness, this change removes all the reference
when coverage measuement is stopped.
