d_splice_alias() does the right thing when given
ERR_PTR(-E...) for inode. No need for gotos, multiple
returns, etc. in there.

Hi,
Frankly, I think it is a straight-forward cleanup by Al enough
to be submitted to Linux 4.20 in constant to other pending fixes
found in the process of EROFS productization these days, which
I need more time to think over and fix formally to the community.
p.s. I have no idea whether this patch has been already queued up
in Al's fs tree for 4.20... :'( +Cc Greg / the staging mailing
list as well. Or please ignore this email...
Thanks,
Gao Xiang
