[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.
