media: Bulk remove BUG_ON(in_interrupt())
None of these BUG_ON()'s is justified. BUG_ON() should only be used when there is really no way to survive. If at all these could be replaced by lockdep_assert_preemption_enabled() to cover all invalid caller context and not just those covered by in_interrupt(). But all functions which are invoked from those places contain already debug mechanisms to catch wrong context, so having these extra checks is not having any advantage.
