[LTP] [PATCH] syscalls/xattr: avoid creating whiteout device

[Eryu Guan]

Do the same as in commit 3337c31d3577 ("syscalls: avoid creating
whiteout device in tests"), because overlayfs refuses to create whiteout
device.

I missed [sg]etxattr02.c in commit 3337c31d3577. After searching around all the
tests I confirmed that [sg]etxattr02.c are the last two places to create
whiteout device.
