staging: r8188eu: don't accept SIGTERM for cmd thread
At the moment, our command thread can be killed by user space.
[root@host ]# kill `pidof RTW_CMD_THREAD`
The driver will then stop working until the module is unloaded
and reloaded.
Don't process SIGTERM in the command thread. Other drivers that have a
command thread don't process SIGTERM either.
