[Bugfix/Auto] Fix the bug to access freed memory region in auto fwname

This patch fixes the memory bug in auto tensor filter detection.

`gst_tensor_filter_get_available_framework` assumes that `fw_name` and
`prop->fwname` are pointing different memory regions.

However, `_gtfc_setprop_Model` has passed the argument `fw_name` as
`prop->fwname`, which may cause the invalid memory access.

In this case, `fw_name` is being accessed after `prop->fwname` is freed.
