feat(esp32s3_i2c): do not destuck every transaction

Browse Source 
It looks like we do not need to send the 9 clock ticks whenever we reset
the FSM. We are already doing this in i2c_reset function if necessary.

This makes the i2c transfers much faster, for example the i2c(-tool) dev
scan feature.
