[SCM] libav/experimental: Replace "signed short" typecast with "int16_t" as suggested by Mans Rullgard. Value at the right side is 16 bit length signed. We can not know for sure that short is in fact 16 bits, even if this virtually always is the case.

    Replace "signed short" typecast with "int16_t" as suggested by
    Mans Rullgard. Value at the right side is 16 bit length signed.
    We can not know for sure that short is in fact 16 bits, even if
    this virtually always is the case.
