Zdenek Kabelac 95d5877f7a cache: add missing udev wait
When we need to clear dirty cache content of cached LV, there
is table reload which usually is shortly followed by next metadata
change.  However  udev  can't (as of now)  process   udev event
while device is 'suspended'.

So whenever sequence of  'suspend/resume/suspend' is needed,
we need to wait first for finishing of 'resume' processing before
starting next 'suspend'. Otherwise there is  'race' danger of triggering
unwantend umount by systemd as  such event will trigger
SYSTEMD_READY=0 state for a moment for such changed device.

Such race is pretty ugly to trace so we may need to review more
sequencies for missing 'sync'.

(Other option is to enhnace 'udev' rules processing to avoid
such dramatic actions to be happening for suspended devices).
