ipv4: Store netns in FIB table
The next patch will stop passing the network namespace to
fib_table_lookup() and instead pass the namespace from the FIB table to
the fib_table_lookup tracepoint. As a preparation, store the namespace
in the FIB table when the table is created.
The FIB table structure grows from 48 bytes to 56 bytes and still fits
in a single cache line.
No functional changes intended.
