CIFS: Fix wrong filename length for SMB2
commit 1bbe4997b13de903c421c1cc78440e544b5f9064 upstream.
The existing code uses the old MAX_NAME constant. This causes
XFS test generic/013 to fail. Fix it by replacing MAX_NAME with
PATH_MAX that SMB1 uses. Also remove an unused MAX_NAME constant
definition.
