smb: client: fix file type corruption in wsl_to_fattr()

Browse Source 
Setting the file type in cf_mode without clearing the existing S_IFMT
bits first is wrong as it corrupts the file type when cf_mode already
has type bits set (e.g. S_IFREG | S_IFCHR == S_IFLNK).

Clear S_IFMT before the switch statement.
