Subject: ratelimit: add ratelimit_state_init()
From: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>

For now, all users of ratelimit_state allocates it statically, so
DEFINE_RATELIMIT_STATE() is enough.  But, I want to use ratelimit_state
for fs, i.e.  per super_block to suppress too many error reports.

So, this adds ratelimit_state_init() to initialize ratelimite_state
which is dynamically allocated, instead of opencoding.
