Don't return the main file as the separate debug info
On Fedora 35,
$ readelf -d /usr/bin/npc
caused readelf to run out of stack since load_separate_debug_info
returned the input main file as the separate debug info:

Return NULL if the separate debug info is the same as the input main
file to avoid infinite recursion.
PR binutils/28679
* dwarf.c (load_separate_debug_info): Don't return the input
main file.
