P2P: Refactor p2p_process_prov_disc_resp() function

Add 'else if' to P2PS status verification to prevent a redundant
condition checking. The first 'if' condition is true only if
  status == P2P_SC_SUCCESS || status == P2P_SC_SUCCESS_DEFERRED.
while the second condition checks:
  status != P2P_SC_SUCCESS &&
  status != P2P_SC_FAIL_INFO_CURRENTLY_UNAVAILABLE &&
  status != P2P_SC_SUCCESS_DEFERRED
Thus, the two conditions are mutually exclusive and 'else if' can be
used if this case.
