[NUCLEO_F103RB] Revert and update path for 16-bit timer 

Due to directory structure change, modification in e93878078 was made wrong
after rebasing the code.

This reverts commit e938780788 and updates path
to the correct file.

Note:
Current value of TIM_MST->CNT is read in interrupt context only.
This avoids master timer overflow without SlaveCounter update.

Continuation of patch: 07b841b08f
