net/ipv4/sysctl_net_ipv4.c: remove superfluous header files from sysctl_net_ipv4.c
sysctl_net_ipv4.c hasn't use any macro or function declared in igmp.h,
inetdevice.h, mm.h, module.h, nsproxy.h, swap.h, inet_frag.h, route.h
and snmp.h. Thus, these files can be removed from sysctl_net_ipv4.c
safely without affecting the compilation of the net module.
