We missed to set file info when CIFSSMBQPathInfo() returned 0, thus
leaving cifs_open_info_data::fi unset.

Fix this by setting cifs_open_info_data::fi when either
CIFSSMBQPathInfo() or SMBQueryInformation() succeed.

Bug: https://bugzilla.kernel.org/show_bug.cgi?id=216881
Fixes: 76894f3e2f71 ("cifs: improve symlink handling for smb2+")
