wifi: iwlwifi: check for kmemdup() return value in iwl_parse_tlv_firmware()

[ Upstream commit 3c8aaaa7 ]

In 'iwl_parse_tlv_firmware()', check for 'kmemdup()' return value
when handling IWL_UCODE_TLV_CURRENT_PC and set the number of parsed
entries only if an allocation was successful (just like it does with
handling IWL_UCODE_TLV_CMD_VERSIONS above). Compile tested only.
