selinux: handle files opened with flags 3 by checking ioctl permission
Handle files opened with flags 3 by checking ioctl permission.
Default to returning FILE__IOCTL from file_to_av() if the f_mode has neither
FMODE_READ nor FMODE_WRITE, and thus check ioctl permission on exec or
transfer, thereby validating such descriptors early as with normal r/w
descriptors and catching leaks of them prior to attempted usage.
