modules: de-mutex more symbol lookup paths in the module code
Kyle McMartin reports sysrq_timer_list_show() can hit the module mutex
from hard interrupt context. These paths don't need to though, since we
long ago changed all the module list manipulation to occur via
stop_machine().
Disabling preemption is enough.
