Bart Van Assche 6d4c93affe blkcg: Unlock blkcg_pol_mutex only once when cpd == NULL ...

commit bbb427e342 upstream.

Unlocking a mutex twice is wrong. Hence modify blkcg_policy_register()
such that blkcg_pol_mutex is unlocked once if cpd == NULL. This patch
avoids that smatch reports the following error:

block/blk-cgroup.c:1378: blkcg_policy_register() error: double unlock 'mutex:&blkcg_pol_mutex'

Fixes: 06b285bd11 ("blkcg: fix blkcg_policy_data allocation bug")
