Krzysztof Kozlowski 107e849f3c nfc: llcp: fix possible use of uninitialized variable in nfc_llcp_send_connect() 
[ Upstream commit 0d9b41daa5907756a31772d8af8ac5ff25cf17c1 ]

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()")
