Thadeu Lima de Souza Cascardo f40ddcc0c0 Revert "nfc/nci: Add the inconsistency check between the input data length and count"

This reverts commit 068648aab7.

NFC packets may have NUL-bytes. Checking for string length is not a correct
assumption here. As long as there is a check for the length copied from
copy_from_user, all should be fine.

The fix only prevented the syzbot reproducer from triggering the bug
because the packet is not enqueued anymore and the code that triggers the
bug is not exercised.

The fix even broke
testing/selftests/nci/nci_dev, making all tests there fail. After the
revert, 6 out of 8 tests pass.
