drivers: i2c: esp32: Fix command opcode on i2c_esp32_write_addr()

When I2C Master writes to slave on CMD_Controller, opcode WRITE
was set twice instead of 1 WRITE at the beginning of the
transmission.

And when Master reads from slave, on CMD_Controller,
byte_num = 1 + data_lenght instead of byte_num = 1 at the
beginning of the transmission.

Note that is for 7 bits addresses, to 10 bit adressess is added
more 1 in byte_num as can be seen in the code above this fix.
