ANDROID: usb: gadget: f_mtp: Return error if count is negative
If the user passes in a negative file size in a int64,
this will compare to be smaller than buffer length,
and it will get truncated to form a read length that
is larger than the buffer length.
To fix, return -EINVAL if the count argument is negative,
so the loop will never happen.
