[PATCH RESEND 03/11] cifs: Remove CIFSSMBSetPathInfoFB() fallback function

[Pali Rohár]

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, since commit f122121796f9 ("cifs: Fix changing
times and read-only attr over SMB1 smb_set_file_info() function") and
commit 92210ccd877b ("cifs: Add fallback code path for cifs_mkdir_setinfo()").

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