hfsplus: fix generic/062 xfstests failure

The xfstests' test-case generic/062 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/062 - output mismatch (see xfstests-dev/results//generic/062.out.bad)

The generic/062 test tries to set and get xattrs for various types
of objects (regular file, folder, block device, character
device, pipe, etc) with the goal to check that xattr operations
works correctly for all possible types of file system objects.
But current HFS+ implementation somehow hasn't support of
xattr operatioons for the case of block device, character
device, and pipe objects. Also, it has not completely correct
set of operations for the case symlinks.

This patch implements proper declaration of xattrs operations
hfsplus_special_inode_operations and hfsplus_symlink_inode_operations.
Also, it slightly corrects the logic of hfsplus_listxattr()
method.
