Fixed two possible memory leaks in the error exit paths of
acpi_ut_update_objerct_reference() and
acpi_ut_walk_package_tree()
These functions are similar in that they use a stack of state objects in
order to eliminate recursion. The stack must be fully deallocated
if an error occurs.

inadvertently declares too many arguments, but does not actually

This is debatable, but while we're debating it, let's disallow the
combination of splice and an O_APPEND destination.

It's not entirely clear what the semantics of O_APPEND should be, and
POSIX apparently expects pwrite() to ignore O_APPEND, for example.  So
we could make up any semantics we want, including the old ones.

But Miklos convinced me that we should at least give it some thought,
and that accepting writes at arbitrary offsets is wrong at least for
IS_APPEND() files (which always have O_APPEND set, even if the reverse
isn't true: you can obviously have O_APPEND set on a regular file).

So disallow O_APPEND entirely for now.  I doubt anybody cares, and this
way we have one less gray area to worry about.

This fixes the previous fix, which was completely wrong on closer

The problem arose from changing how kmalloc/kfree handled alignment
