[lvm-devel] [PATCH 3/4] Do not check already checked part

[Zdenek Kabelac]

check_lv_segments is eithe called once - with 'complete_vg == 0'
or twice in row first with == 0, then with 1.

My assumtion is we do not need to make the same tests for same data
pointers twice - if we already know it's been been OK from the
first pass - that way it's used in vg_validate() and vg_read_internal().

Better idea would be probably to make rather 2 separte functions
there - but for now just skip some large piece of the code.
