mirror: extend adjusted_mirror_region_size API

Browse Source 
We use adjusted_mirror_region_size() in two different contexts.

Either on command line -
 here we do want to inform user about reduction of size.

Or in pvmove activation context -
 here we should only use 'verbose' info.

Version 2.02.112 -
=====================================
Don't print message in adjusted_mirror_region_size() in activation.
Improve lv_update_and_reload() to find out proper lock holding LV.
Improve search of LV in lv_ondisk().
Do not scan sysfs in lv_check_not_in_use() when device is closed.
