(cherry picked from commit 788ef8f07c75d5e6eca5b8f18d93d96f31574267)
[noel.power@suse.com backported to Samba 4.19 changed test of errno
    after return from widelink_openat to ENOENT because ELOOP isn't set
    for msdfs links in 4.19, ENOENT is set instead. Also minor change
    to use 4.19 create_open_symlink_err fn instead of read_symlink_reparse]
