Richard Henderson ad17868eb1 accel/tcg: Clear tcg_ctx->gen_tb on buffer overflow
On overflow of code_gen_buffer, we unlock the guest pages we had been
translating, but failed to clear gen_tb.  On restart, if we cannot
allocate a TB, we exit to the main loop to perform the flush of all
TBs as soon as possible.  With garbage in gen_tb, we hit an assert:

../src/accel/tcg/tb-maint.c:348:page_unlock__debug: \
    assertion failed: (page_is_locked(pd))

Fixes: deba78709a ("accel/tcg: Always lock pages before translation")
