libdm: do not fail if GETVAL semctl fails for udev sync inc and dec 
While performing udev sync semaphore's inc/dec operation, we use the
result from GETVAL semctl just to print a debug message with current
value of that sempahore, nothing else.

If the GETVAL fails for whetever reason while the actual inc/dec
completes successfully, just log a warning message about the GETVAL
(and print the debug messages without the actual semaphore value)
and return success for the inc/dec operation as a whole.

libdm: clean up udev sync semaphore on fail path during its creation 
Clean up udev sync semaphore on fail path during its creation, otherwise
the caller will have no handle returned to clean it up itself and the
semaphore will keep staying in the system. The only way to clean it up
would be to call `dmsetup udevcomplete_all` which would destroy all
udev sync semaphores, not just the failed one, which we don't want.

libdm: add 'cookie create/inc/dec' log prefix if GETVAL fails for udev sync ops 
The same message is printed while performing create/inc/dec operation and
the GETVAL semctl fails. Add a prefix so we know exactly in which of
these functions the issue actually happened.

This reverts commit d16a8f80e9.
So the correction was OK, however we missed to fix also
cut&paste bug here - as the second check should be
actually checking  field->type.
