[PATCH RESEND v2 5/5] block/partitions/ldm: Remove redundant assignments

[Michal Orzel <michalorzel.eng@xxxxxxxxx>]

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.

Reported by clang-tidy [deadcode.DeadStores]
