smb: client: fix incomplete backport in cfids_invalidation_worker()

Browse Source 
The previous commit bdb596ceb4 ("smb: client: fix potential UAF in
smb2_close_cached_fid()") was an incomplete backport and missed one
kref_put() call in cfids_invalidation_worker() that should have been
converted to close_cached_dir().

Fixes: bdb596ceb4 ("smb: client: fix potential UAF in smb2_close_cached_fid()")"
