[PATCH] [media] pvrusb2: qctrl.flag will be uninitlaized if cx2341x_ctrl_query() returns error code

[Yizhuo]

Inside function ctrl_cx2341x_getv4lflags(), qctrl.flag
will be uninitlaized if cx2341x_ctrl_query() returns -EINVAL.
However, it will be used in the later if statement, which is
potentially unsafe.
