[STM32F4] Master receive sequential - fix for HAL I2C 

in case of 2 consecutives calls to HAL_I2C_Master_Sequential_Receive_IT
with the Xfer mode I2C_FIRST_AND_LAST_FRAME, the second trasnfer does
not start at all.

It seems this is because the previous state is maintained as I2C_STATE_MASTER_BUSY_RX
and therefore the START condition will not be generated
