dmsetup: fix udev event handling for create
With newer kernels (>5.13) DM_CREATE no longer generates
uevent for DM devices without table.
There are even no sysfs block device entries in such case,
although device has asigned major:minor and it is being listed
by 'dmsetup info'.
So this patch calculates amount of 'table' lines and in case
no table line comes from cmdline or stdin - waiting on cookie
is avoided generically instead of disabling just case with
option --notable - which then also skipped handling of an
option --addnodeoncreate (which is however historical and
should be avoided)
As a result there should be no leaking udev cookies and endlessly
waiting commands like this:
dmsetup create mytestdev </dev/null
