Cache check close RO opened device before reopen.

Browse Source 
When check_check is used with --clear-needs-check-flag option,
device needs to be opened in RW exclusive mode, but for this
existing RO exlusive open must be closed.

LVM2 will consider version 0.5.3 as a version without flag support
for cache_check since it cannot successfully pass cache_check.

TODO: when 'RO' parts detects there is nothing to 'clear' it should
completely skip RW open to avoid udev rule processing.
