dev: Close socket in error path of device_ifindex_get()
If the ioctl() fails, the socket still needs to be closed instead of returning directly. This issue was discovered using the Coverity scanner. Fixes: f43bbe9 ("mac80211: Check existence of generated monX device") Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

tracing: Fix hwlat kthread migration
The hwlat tracer creates a kernel thread at start of the tracer. It is pinned to a single CPU and will move to the next CPU after each period of running. If the user modifies the migration thread's affinity, it will not change after that happens. The original code created the thread at the first instance it was called, but later was changed to destroy the thread after the tracer was finished, and would not be created until the next instance of the tracer was established. The code that initialized the affinity was only called on the initial instantiation of the tracer. After that, it was not initialized, and the previous affinity did not match the current newly created one, making it appear that the user modified the thread's affinity when it did not, and the thread failed to migrate again.
