Zhang Huan 37796aa7bf blkdeactive: Introduce option "forcevg" to forcibly deactivate VG
This patch introduces new option "forcevg" for LVM, the main purpose is
to flush in-flight I/O operations and replace the LV's device mapper
table with 'error' target, this is accomplished by using command
"dmsetup wipe_table".

To handle the failure as soon as possible, it will not deactivate
holders and not try to use command "lvchange", thus can speed up
wiping table.

This option is supposed to be used by "lvmlockctl" command to forcibly
deactivate volume group, this can avoid watchdog reset when detect
drive failures.
