vlan: Fix musl build error

Browse source 
caddr_t is legacy BSD and should be avoided [1]. While glibc may still
use __caddr_t as the type, Linux kernel does not (it is "void __user *
ifru_data").

This fixes compile errors with the musl libc:

../src/ap/vlan_init.c: In function 'br_delif':
../src/ap/vlan_init.c:218:18: error: '__caddr_t' undeclared (first use in this function)
  ifr.ifr_data = (__caddr_t) args;
