Kuniyuki Iwashima 4b8f5c974d ipv4: fib: Protect fib_new_table() with spinlock. ...

fib_newrule() will drop RTNL except for the first IPv4 rule.

Then, fib4_rule_configure() could call fib_empty_table() and create
a new IPv4 fib_table without RTNL.

Currently, net->ipv4.fib_table_hash[] is only protected by RTNL.

As a prep, let's protect net->ipv4.fib_table_hash[] with a dedicated
spinlock.
