[PATCH] memcg: replace in_interrupt() with !in_task()

[Shakeel Butt <shakeelb@google.com>]

Replace the deprecated in_interrupt() with !in_task() because
in_interrupt() returns true for BH disabled even if the call happens in
the task context. in_task() is the right interface to differentiate
task context from NMI, hard IRQ and softirq contexts.
