zebra: Keep the interface flags safe on multiple ioctl calls

Trying to call multiple ioctl calls on ifreq will result in
overwriting ifreq with garbage data. On if_get_flags call,
try to keep the flags field safe from another possible ioctl
call before applying the flags field.

Modified code as per Code Review, done by Donald Sharp.
