block/partitions/ldm: Remove redundant assignments
Get rid of the following redundant assignments:
- to a variable r_cols from function ldm_parse_cmp3
- to variables r_id1 and r_id2 from functions ldm_parse_dgr3 and ldm_parse_dgr4
- to a variable r_index from function ldm_parse_prt3
that end up in values not being read until the end of function.
