Modified Files:
        src/sys/dev/pci: alipm.c

Log Message:
Since there are no RW_READERs for the device's rw_lock, convert it to a
mutex and reduce the overhead.

Also, even if we're polling, we need to use the lock to control access to
the bus, otherwise we get anomolous results.

(These same changes were made several weeks ago to other drivers;  I
missed this one.)
