nfc: llcp: fix possible use of uninitialized variable in nfc_llcp_send_connect()
If sock->service_name is NULL, the local variable
service_name_tlv_length will not be assigned by nfc_llcp_build_tlv(),
later leading to using value frmo the stack. Smatch warning:
net/nfc/llcp_commands.c:442 nfc_llcp_send_connect() error: uninitialized symbol 'service_name_tlv_length'.
Fixes: de9e5aeb4f40 ("NFC: llcp: Fix usage of llcp_add_tlv()")
