[lvm-devel] [PATCH 11/30] Update devsize_disp() to call liblvm 'get' function.

[Dave Wysochanski]

Should be no functional change.
Note again we change the field data pointer from 'dev' to 'id' so that
the 'data' pointer value is simply the pointer to the 'pv'.  We can then
call the liblvm 'get' function to retrieve the value.
