[PATCH v6 08/20] modpost: remove is_shndx_special() check from section_rel(a)

[Masahiro Yamada]

This check is unneeded. Without it, sec_name() will returns the null
string "", then section_mismatch() will return immediately.

Anyway, special section indices rarely appear in these loops.

Changes in v6:
  - Remove is_shndx_special() definition
