We will allocate the fib_info hash tables per netns.
There are 5 global variables for fib_info hash tables:
fib_info_hash, fib_info_laddrhash, fib_info_hash_size,
fib_info_hash_bits, fib_info_cnt.
However, fib_info_laddrhash and fib_info_hash_size can be
easily calculated from fib_info_hash and fib_info_hash_bits.
Let's remove the fib_info_laddrhash pointer and instead use
fib_info_hash + (1 << fib_info_hash_bits).
While at it, fib_info_laddrhash_bucket() is moved near other
hash-table-specific functions.
