debug: show proper error message for layer mismatch

Browse Source 
Show proper internal error for failing command when there are some
inconsitencies in sizes of LV and its layer instead of rather
meaningless error code 5.

(Could be hit i.e. if user tried to 'resize' cached LV and then
uncache such LV.)
