[PATCH] iproute2: fix broken get_prefix_1

[PATCH] iproute2: fix broken get_prefix_1

[Joe Harvell]

Fixes bug that causes a basic 'ip addr add' command to fail address due 
to the address prefix is incorrectly determined to be invalid.

I assume master must have some new change because this fix was needed 
for a basic 'ip addr add 10.0.3.1/24 dev dumbo label foo' command I 
pased in.  In this case, 'family' passed into get_addr_1 two lines above 
is zero, causing get_addr_1 to detect the family from the address and 
populate the result in the family field in dst.  But then instead of 
passing in the result, family (still 0) is passed in to af_bit_len. 
Without my change, the above command complains that 10.0.3.1/24 is not 
an address prefix.  With the change it works fine as expected.
