of each card
Generally ALSA control devices should be the last ones to be processed
for ACL changes and similar operations because they can then be used as
indicators that ACL management finished for all device nodes of a
specific card.
This patch simple moves each controlC device behind all the pcmC devices
(and similar).

On machines with many thousands of devices:
$ time find /sys -name uevent | wc -l
74876
real 0m33.171s
user 0m3.329s
sys 0m29.719s
the current udevtrigger spends minutes sorting the device list:
$ time /sbin/udevadm trigger --dry-run
real 4m56.739s
user 4m45.743s
sys 0m7.862s
with qsort() it looks better:
$ time udev/udevadm trigger --dry-run
real 0m6.495s
user 0m0.473s
sys 0m5.923s
