Static analysis tools get annoyed that we don't indent this if
statement.  Actually, the if statement isn't required because kfree()
can handle NULL pointers just fine.  The DCE110STRENC_FROM_STRENC()
macro is a wrapper around container_of() but it's basically a no-op or a
cast.  Anyway, it's not really appropriate here so it should be removed
as well.
