[media] dib0700: Return -EINTR and unlock mutex if locking attempts fails
In 'dib0700_i2c_xfer_new()' and 'dib0700_i2c_xfer_legacy()' we are taking two locks: 1. i2c_mutex 2. usb_mutex If attempt to take 'usb_mutex' lock fails then the previously taken lock 'i2c_mutex' should be unlocked and -EINTR should be returned so that caller can take appropriate action. If locking attempt was interrupted by a signal then we should return -EINTR. At present we are returning '0' for such scenarios which is wrong. Replace -EAGAIN by -EINTR as a return type for the the scenario where locking attempt was interrupted by signal.
