[committed] BFD/PA: Remove ATTRIBUTE_UNUSED from `elf_hppa_info_to_howto_rel'

[Maciej W. Rozycki]

Remove ATTRIBUTE_UNUSED annotation from the `abfd' parameter in 
`elf_hppa_info_to_howto' now that commit f3185997ac09 ("PR 22875: Stop 
strip corrupting unknown relocs"), 
<https://sourceware.org/ml/binutils/2018-02/msg00445.html>, made it 
used.

	bfd/
	* elf-hppa.h (elf_hppa_info_to_howto_rel): Remove 
	ATTRIBUTE_UNUSED from `abfd'.
