dmsetup: report error on stderr

Browse Source 
Send error message on stdout, since after _display_info_long()
command return errors.

Patch makes consistent behavior for command:

dmsetup info -c non-existing-dev
&
dmsetup info non-existing-dev

Now both commands report error on stderr when they return error status
for non-existing device.

==================================
Consistently report on stderr when device is not found for dmsetup info.
Skip race errors when non-udev dmsetup build runs on udev-enabled system.
Skip error message when holders are not present in sysfs.
Use __linux__ instead of linux define to make libdevmapper.h C compliant.
