Fix a race condition around mjit_recompile
This fixes SEGVs like https://github.com/ruby/ruby/runs/2715166621?check_suite_focus=true.
When mjit_recompile is called when mjit_compile is compiling the exact
same iseq (and after it called mjit_capture_cc_entries), iseq->body->jit_unit
is re-created and its cc_entries becomes NULL. Then, when it tries to
lookup cc_entries through iseq->body->jit_unit, it fails.
