This is in preparation of adding an additional setting for this
option. No change in behaviour by this commit, that comes in the next
one.

76360caad2 s3/smbd: use stat from smb_fname if valid in refuse_symlink()
Now that refuse_symlink() gets passed in a smb_fname and not just a char
buffer, we can try to reuse its stat info and save one stat call here.

b13b3c1105 s3/smbd: in call_trans2qfilepathinfo call lstat when dealing with posix pathnames
This might be an info level SMB_INFO_QUERY_ALL_EAS which is not covered
by INFO_LEVEL_IS_UNIX(). If smb_fname is a symlink we would then stat it
in POSIX context.

bd2ec88dca smbd: get a valid file stat to disk_quotas
Most calls to disk_quotas originate at a state with an
open file descriptor. Pass the file's stat info down to
disk_quota, so that we can avoid extra stat's and the related
error handling.
