STM32 I2Cv1 async write_read skips sending the last byte

[sandermirme]

The async I2C write_read command skips the last byte of the specified send buffer, unless the buffer contains only one byte.
Everything works correctly when the command is split into separate write and read.

MCU: STM32F407VGT which uses I2Cv1 implementation

Here are some commands and the resulting logic analyzer traces:

1. Calling with two bytes actually sends one

i2c.write_read(0x28, &[0xe1, 0x02], &mut buf).await

2. Calling with three bytes actually sends two

i2c.write_read(0x28, &[0xe1, 0x02, 0x03], &mut buf).await

3. Calling with one bytes sends one

i2c.write_read(0x28, &[0xe1], &mut buf).await
