[linux-nfc] [PATCH v2 6/6] nfc: llcp: Revert "NFC: Keep socket alive until the DISC PDU is actually sent"

This reverts commit 17f7ae16aef1f58bc4af4c7a16b8778a91a30255.

The commit brought a new socket state LLCP_DISCONNECTING, which was
never set, only read, so socket could never set to such state.

Remove the dead code.
