autofs4: Do not potentially dereference NULL pointer returned by fget() in autofs_dev_ioctl_setpipefd()
In fs/autofs4/dev-ioctl.c::autofs_dev_ioctl_setpipefd() we call fget(), which may return NULL, but we do not explicitly test for that NULL return so we may end up dereferencing a NULL pointer - bad. When I originally submitted this patch I had chosen EBUSY as the return value to use if this happens. Ian Kent was kind enough to explain why that would most likely be wrong and why EBADF should most likely be used instead. This version of the patch uses EBADF.
