David Sidrane acaebb361b STM32, STM32 F7, and STM32 L4: Clone Freddie Chopin's I2C change to similar STM32 I2C drivers. 
Save elapsed time before handling I2C in stm32_i2c_sem_waitstop()
   This patch follows the same logic as in previous fix to
   stm32_i2c_sem_waitdone().
   It is possible that a context switch occurs after I2C registers are read
   but before elapsed time is saved in stm32_i2c_sem_waitstop(). It is then
   possible that the registers were read only once with "elapsed time"
   equal 0. When scheduler resumes this thread it is quite possible that
   now "elapsed time" will be well above timeout threshold. In that case
   the function returns and reports a timeout, even though the registers
   were not read "recently".
   Fix this by inverting the order of operations in the loop - save elapsed
   time before reading registers. This way a context switch anywhere in the
   loop will not cause an erroneous "timeout" error.
