vzlist: do not use /proc/bc/resources for non-running CTs
For stopped CTs, UBC parameters should NOT be obtained from
/proc/bc/resources. Since /proc/bc/resources do not usually
list stopped CTs, this usually never happens.
In some rare cases though a container is stopped but for some
of its beancounters held value is not zero (such as because
of a kernel bug in UBC accounting), and its UBC entry remains.
In such a case, values from the proc file should not be used,
UBCs values (barrier and limit) should be obtained from the
CT config file. Otherwise we can have this:
# vzlist 101 -o physpages.l
PHYSP.L
524288
# vzctl set 101 --ram 10G --save
CT configuration saved to /etc/vz/conf/101.conf
# vzlist 101 -o physpages.l
PHYSP.L
524288 <<<<=== Old/wrong value shown here
# vzctl start 101
...
Container start in progress...
# vzlist 101 -o physpages.l
PHYSP.L
