Remove check for ploop size

Remove check_ploop_size() introduced by commit 6905fc7, letting
ploop library decide what size is supported.

The reason for commit 6905fc7 was some people mistakenly had
'unlimited' as a value for DISKSPACE parameter in config.

The proper fix would be to error out once we see 'unlimited' --
implemented in the next commit.
