smb: client: Remove an unused function and variable 

SMB2_QFS_info() has been unused since 2018's
commit 730928c8f4 ("cifs: update smb2_queryfs() to use compounding")

sign_CIFS_PDUs has been unused since 2009's
commit 2edd6c5b05 ("[CIFS] NTLMSSP support moving into new file, old dead
code removed")

Remove them.
