madvise() terminates application due to EBADF code

    Description

      After QTBUG-100431 the application crashes if the call

      madvise(address, bytes, MADV_WILLNEED)

      returned an EBADF error.

      There is no swap on our systems. I assume that in such conditions there is no need to terminate the application on an EBADF error.
