module: Remove module_assert_mutex_or_preempt() from try_add_tainted_module().

module_assert_mutex_or_preempt() is not needed in
try_add_tainted_module(). The function checks for RCU-sched or the
module_mutex to be acquired. The list_for_each_entry_rcu() below does
the same check.

Remove module_assert_mutex_or_preempt() from try_add_tainted_module().
