Before this fix, when reporting 'lvm devtypes', the report was
initialized with incorrect reserved values - the ones used for
pvs/vgs/lvs report were used instead of NULL value (because devtypes
doesn't have any reserved values).
For example, trying to (incorrectly) use lv_name for the -S|--select
with lvm devtypes which doesn't have this field at all:
Before this patch (internal error issued):
$ lvm devtypes -S 'lv_name=lvol0'
Internal error: _check_reserved_values_supported: field-specific reserved value of type 0x0 for field not supported
Internal error: dm_report_init_with_selection: trying to register unsupported reserved value type, skipping report selection
DevType MaxParts Description
aoe 16 ATA over Ethernet

unrecognized selection field):
$ lvm devtypes -S 'lv_name=lvol0'
