After boot, all lvm actions hang waiting for response from lvmetad.

Investigation shows that lvmetad hangs waiting for a lock. "systemctl restart
lvm2-lvmetad" is sufficient as workaround, but it's annoying to have to do this
after every reboot.

Reproducible: Always

Steps to Reproduce:
1. boot

Actual Results:
all lvm operations hang, see above.

Expected Results:
lvm operations should work normally

syslog shows that lvm commands called by udev time out already:

Apr 25 22:49:53 psyche.mittagstun.de systemd-udevd[402]: timeout: killing
'/sbin/lvm pvscan --cache --activate ay --major 8 --minor 10' [534]
Apr 25 22:49:53 psyche.mittagstun.de systemd-udevd[402]: '/sbin/lvm pvscan
--cache --activate ay --major 8 --minor 10' [534] terminated by signal 9
(Killed)
