hfsplus: fix generic/533 test-case failure

Browse source 
The xfstests' test-case generic/533 fails to execute
correctly:

FSTYP -- hfsplus
PLATFORM -- Linux/x86_64 hfsplus-testing-0001 6.15.0-rc4+ #8 SMP PREEMPT_DYNAMIC Thu May 1 16:43:22 PDT 2025
MKFS_OPTIONS -- /dev/loop51
MOUNT_OPTIONS -- /dev/loop51 /mnt/scratch

generic/533 _check_generic_filesystem: filesystem on /dev/loop50 is inconsistent
(see xfstests-dev/results//generic/533.full for details)

The key reason of the issue is returning -ENOENT error
code from hfsplus_find_attr(), __hfsplus_delete_attr(),
hfsplus_delete_attr_nolock(), hfsplus_delete_all_attrs().
The file exists but we don't have any xattr for this file.
Finally, -ENODATA error code is expected by application logic.

This patch reworks xattr logic of HFS+ by means exchanging
the -ENOENT error code on -ENODATA error code if xattr
has not been found for existing file or folder.

sudo ./check generic/533
FSTYP         -- hfsplus
PLATFORM      -- Linux/x86_64 hfsplus-testing-0001 7.0.0-rc1+ #16 SMP PREEMPT_DYNAMIC Wed Mar 11 15:04:58 PDT 2026
MKFS_OPTIONS  -- /dev/loop51
MOUNT_OPTIONS -- /dev/loop51 /mnt/scratch
