[ELF] -r: fix crash when processing a SHT_REL[A] that relocates a SHF_MERGE after D67504/r372734
Fix PR43767
In -r mode, when processing a SHT_REL[A] that relocates a SHF_MERGE, sec->getRelocatedSection() is a
MergeInputSection and its parent is an OutputSection but is asserted to
be a SyntheticSection (MergeSyntheticSection) in LinkerScript.cpp:addInputSec().
##
The code path is not exercised in non -r mode because the relocated
section changed from MergeInputSection to InputSection.
Reorder the code to make the non -r logic apply to -r as well, thus fix
the crash.
