target-xtensa: don't emit extra tcg_gen_goto_tb
Unconditional gen_check_loop_end at the end of disas_xtensa_insn can emit tcg_gen_goto_tb with slot id already used in the TB (e.g. when TB ends at LEND with a branch). Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Cc: qemu-stable <qemu-stable@nongnu.org> Signed-off-by: malc <av1474@comtv.ru>
