nfc: trf7970a: Use NULL when no response is expected

Browse source

When a command's timeout is zero, no response is expected, and the TX
interrupt handler completes the command by passing ERR_PTR(0) to the
digital callback.

ERR_PTR(0) evaluates to NULL, so no errno is encoded here.  Use NULL
directly to avoid suggesting that this is an error-pointer path.
