The proc_create() and remove_proc_entry() functions do not reference
their arguments when CONFIG_PROC_FS is disabled, so we get a couple
of warnings about unused variables in IPVS:
ipvs/ip_vs_app.c:608:14: warning: unused variable 'net' [-Wunused-variable]
ipvs/ip_vs_ctl.c:3950:14: warning: unused variable 'net' [-Wunused-variable]
ipvs/ip_vs_ctl.c:3994:14: warning: unused variable 'net' [-Wunused-variable]
This removes the local variables and instead looks them up separately
for each use, which obviously avoids the warning.
