netdev-bsd: Fix sign extension bug in ifr_flags on FreeBSD.

FreeBSD fills the int return value with ifr_flagshigh in the high
16 bits and ifr_flags in the low 16 bits rather than blindly promoting
ifr_flags to an int, which will preserve the sign.
This commit makes sure the flags returned isn't negative and apply mask
0xffff to flags.
