Subject: [PATCH] cifs: Fix a tiny potential memory leak
Git-commit: c715f89c4dab76317c773df2611af2dac4dea2b7
Patch-mainline: v5.0-rc2
References: bsc#1144333

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")
