risc-v/esp32-c3: fix pid initiatialization on esp32c3_rt_timer.c 

pid variable was initialized to -EINVAL to prevent rt_timer_deinit
from delete an invalid kthread. But priv->pid was being overwritten in the
rt_timer_init, so in case of failure to create a kthread, it would
call rt_timer_deinit with a non expected initialization value.
