samples: net sockets coap_upload: Be explicit about offsetting pointer

aescolar · aescolar · commit 2033bbca06b1 · 2026-07-23T11:53:29.000+02:00
Let's be explicit about offsetting the pointer into the string,
to avoid a warning by the compiler in code it considers may be
a programming bug:

  error: adding 'size_t' (aka 'unsigned int') to a string does not
  append to the string
