vfs: Remove incorrect debugging WARN in prepend_path
commit 93e3bce6287e1fb3e60d3324ed08555b5bbafa89 upstream.
The warning message in prepend_path is unclear and outdated. It was
added as a warning that the mechanism for generating names of pseudo
files had been removed from prepend_path and d_dname should be used
instead. Unfortunately the warning reads like a general warning,
making it unclear what to do with it.
Remove the warning. The transition it was added to warn about is long
over, and I added code several years ago which in rare cases causes
the warning to fire on legitimate code, and the warning is now firing
and scaring people for no good reason.
