Subject: [PATCH 12/12] cifs: Remove CIFSSMBSetPathInfoFB() fallback function

This fallback function CIFSSMBSetPathInfoFB() is called only from
CIFSSMBSetPathInfo() function. CIFSSMBSetPathInfo() is used in
smb_set_file_info() which contains all required fallback code, including
fallback via filehandle.

So the CIFSSMBSetPathInfoFB() is just code duplication, which is not needed
anymore. Therefore remove it.

This change depends on other changes which are extending
cifs_mkdir_setinfo() and smb_set_file_info() functions.
