USB: ums_realtek: do not use stack memory for DMA in __do_config_autodelink
__do_config_autodelink passes the data variable to the transport function.
If the calling functions pass a stack variable, this will eventually trigger
a DMA-API debug backtrace for mapping stack memory in the DMA buffer. Fix
this by calling kmemdup for the passed data instead.
