iwlwifi: fix locking assertions
spin_is_locked() can return zero on some (UP?)
configurations because locks don't exist, and
that causes an endless amount of warnings. Use
lockdep_assert_held() instead, which has two
advantages:
1) it verifies the current task is holding
the lock or mutex
2) it compiles away completely when lockdep
is not enabled
