net: fix possible deadlock in sum_frag_mem_limit
Dave Jones reported a lockdep splat occurring in IP defrag code.
commit 6d7b857d541ecd1d (net: use lib/percpu_counter API for
fragmentation mem accounting) added a possible deadlock.
Because percpu_counter_sum_positive() needs to acquire
a lock that can be used from softirq, we need to disable BH
in sum_frag_mem_limit()
