cifs_setattr_nounix has two paths which miss free operations
for xid and fullpath.
Use goto cifs_setattr_exit like other paths to fix them.
Fixes: aa081859b10c ("cifs: flush before set-info if we have writeable handles")

Looks good, thanks.

The original patch was tagged for stable, so, it seems that this one
should be tagged too.
