H A Dsmb2inode.c33f73618 Thu Jun 22 13:16:03 CDT 2023 Shyam Prasad N <sprasad@microsoft.com> cifs: prevent use-after-free by freeing the cfile later

In smb2_compound_op we have a possible use-after-free
which can cause hard to debug problems later on.

This was revealed during stress testing with KASAN enabled
kernel. Fixing it by moving the cfile free call to
a few lines below, after the usage.
