cpu-exec: rename have_tb_lock to acquired_tb_lock in tb_find

Browse source 
Reusing the have_tb_lock name, which is also defined in translate-all.c,
makes code reviewing unnecessarily harder.

Avoid potential confusion by renaming the local have_tb_lock variable
to something else.

Backports commit 841710c78e022cbc1f798cced035789725702dac from qemu
