lockdep: Fix trace_hardirqs_on_caller()

Browse source

Commit dd4e5d3ac4 ("lockdep: Fix trace_[soft,hard]irqs_[on,off]()
recursion") made a bit of a mess of the various checks and error
conditions.

In particular it moved the check for !irqs_disabled() before the
spurious enable test, resulting in some warnings.
