LSP ping: Fix "Unused value" warnings from Coverity

This change should fix the following Coverity Scan issues:

CID 1397795 (#1 of 1): Unused value (UNUSED_VALUE)
assigned_pointer: Assigning value from tlv_tptr + 4UL to tlv_tptr here,
but that stored value is overwritten before it can be used.

CID 1397796 (#1 of 1): Unused value (UNUSED_VALUE)
assigned_value: Assigning value from tlv_tlen - 4UL to tlv_tlen here,
but that stored value is overwritten before it can be used.

(cherry picked from commit 98145e4ca7e59bfa5c181842c11bd41e98185152)
