ovs_frag_data_storage is a per-CPU variable and relies on disabled BH for its
locking. Without per-CPU locking in local_bh_disable() on PREEMPT_RT
this data structure requires explicit locking.

Move ovs_frag_data_storage into the struct ovs_pcpu_storage which already
provides locking for the structure.
