Subject: [PATCH] revert(lvm): remove lvmetad config changes

Remove support for modifying use_lvmetad and locking_type
settings in lvm.conf for lvm versions 2.2.*.  Recent lvm
versions (2.3.*) do not include lvmetad or locking_type.
This cleanup simplifies code maintenance.

To use the lvm module with older versions (2.2), a user
would need to ensure that lvmetad settings are disabled
in the initrd's lvm.conf rather than relying on the lvm
dracut mode to modify their lvm.conf.
