ide: remove BUG_ON(in_interrupt() || irqs_disabled()) from ide_unregister()
In the discussion about preempt count consistency across kernel
configurations:
https://lore.kernel.org/r/20200914204209.256266093@linutronix.de/
it was concluded that the usage of in_interrupt() and related context
checks should be removed from non-core code.
Both BUG_ON()s in ide-probe.c were introduced in commit
4015c949fb465 ("[PATCH] update ide core")
when ide_unregister() was extended with semaphore based locking. Both
checks won't complain about disabled preemption which is also wrong.
The might_sleep() in today's mutex_lock() will complain about the
missuses.
Remove the BUG_ON() statements.
