We recently introduce new continue in the loop which make gcc complain.
In theory if MTIP_FLAG_SVC_THD_ACTIVE_BIT is set, we could hit continue
over and over until eventually we time out of the loop.  In that case
"active" should be set as true, but right now it's uninitialized.

Do the conversion/copy up front instead of passing in a compat flag
to the ioctl handler and subsequently to the exec_drive_taskfile()
function.

We need to clean up the compat ioctl handling, but this makes it
work for now at least.
