[PATCH] cifs: Fix a tiny potential memory leak

[Dan Carpenter <dan.carpenter@oracle.com>]

The most recent "it" allocation is leaked on this error path.  I
believe that small allocations always succeed in current kernels so
this doesn't really affect run time.

Fixes: 54be1f6c1c37 ("cifs: Add DFS cache routines")
