Fix unused variable warning in iflib.c
With clang 15, the following -Werror warning is produced:
sys/net/iflib.c:993:8: error: variable 'n' set but not used [-Werror,-Wunused-but-set-variable]
u_int n;
^
The 'n' variable appears to have been a debugging aid that has never
been used for anything, so remove it.
