iwlwifi: check allocated pointer when allocating conf_tlvs

Browse Source 
We were erroneously checking the length of the tlv instead of checking
the pointer returned by kmemdup() when allocating dbg_conf_tlv[].
This was probably a typo.  Fix it by checking the returned pointer
instead of the length.
