[PATCH] [CIFS] Remove unneeded check for tcon in SMB2_flush

[PATCH] [CIFS] Remove unneeded check for tcon in SMB2_flush

[Raphael Geissert]

While poking at the code I found what looks like a leftover check for
tcon in SMB2_flush.

SMB2_flush dereferences tcon->ses at the beginning of the function, but
later one it checks for ((rc != 0) && tcon).
All the code in between appears to properly check tcon for NULLness,
but the only caller I found via ops->flush also dereferences tcon on
its own.
