  Changed paths:
    M cpu/stm32/periph/qdec.c

  Log Message:
  cpu/stm32/qdec: test null callback pointer (#14125)

cpu/stm32/qdec: test if callback pointer is set

Callback pointer is not tested and could result in a hard fault
if the pointer is NULL.
Thus only activate interrupt if a callback provided.
