If smb2_compound_op() is called with a valid @cfile and returned
-EINVAL, we need to call cifs_get_writable_path() before retrying it
as the reference of @cfile was already dropped by previous call.

This fixes the following KASAN splat when running fstests generic/013
against Windows Server 2022:

  CIFS: Attempting to mount //w22-fs0/scratch
