Replace size_t with __kernel_size_t to fix definition of struct
sockaddr_nfc_llcp on architectures like x32 and mips n32 where
sizeof(size_t) < sizeof(__kernel_size_t).

This also fixes the following linux/nfc.h userspace compilation error:

/usr/include/linux/nfc.h:279:2: error: unknown type name 'size_t'
  size_t service_name_len;
