ve/printk: fix error handling in ve_log_init
On succesful setup_log_buf_ve we should not free log and return 0,
that's wrong. This leads to zero log_state on succesful ve start and
leads to crash in ve_log_destroy.

Fixes: 40428a8d4e0b ("ve/printk: Introduce struct "log_state" and
virtualize log_buf/log_buf_len")
