modpost: Get proper section index by get_secindex() instead of st_shndx
(uint16_t) st_shndx is limited to 65535(i.e. SHN_XINDEX) so sym_get_data() gets
wrong section index by st_shndx if requested symbol contains extended section
index that is more than 65535. In this case, we need to get proper section index
by .symtab_shndx section.
Module.symvers generated by building kernel with "-ffunction-sections -fdata-sections"
shows the issue.
Fixes: 56067812d5b0 ("kbuild: modversions: add infrastructure for emitting relative CRCs")
Fixes: e84f9fbbece1 ("modpost: refactor namespace_from_kstrtabns() to not hard-code section name")
