Subject: [PATCH 6/8] net: qualcomm: rmnet: get rid of a variable in rmnet_map_ipv4_ul_csum_header()

The value passed as an argument to rmnet_map_ipv4_ul_csum_header()
is always an IPv4 header.  Just have the type of the argument
reflect that rather than obscuring that with a void pointer.  Rename
it to be consistent with rmnet_map_ipv6_ul_csum_header().
