DBUG_RETURN was missing form an exit path in 5.1 branch of alloc_root

The problem was that symlink.test failed due to debug assertions or
due to errors emitted for wrong statements (in non-debug builds)
if 6.0 version of server was run with --thread-handling=pool-of-threads
option.

The above problems were caused by that on the one hand code mi_create()
which handles case when error is returned relies on my_errno being set
to appropriate non-0 value, but on the other it has not done this
in case when error was emitted due to discovery that share for table
which we are going to create is already present in the list of open
shares. Running server with pool-of-threads option just exposed this
bug since in this scheduler mode my_errno is reset to 0 when connection
(THD) is reattached to the "real" thread.

This fix ensures that code in mi_create() properly sets my_errno in
the case described above.

Since original reason that caused this bug to be exposed in 6.0 tree
might also under very special conditions lead to incorrect behavior
of earlier versions of server (i.e. to errors emitted for wrong
statements) this patch is also being pushed into 5.1 tree.

No test case is present as this code is already covered by a test
case + pushbuild options combination in 6.0.

This is a code clean up.
Removed redundant (and unused) TABLE_LIST variable intended as an IN-
parameter for setup_order.

tables is not zero any more. For row-based logging, there is an extra commit
for sending rows changed by the statement to the binary log.

If a binlog file is manually replaced with a namesake directory the internal purging did
not handle the error of deleting the file so that eventually
a post-execution guards fires an assert.

Fixed with reusing a snippet of code for bug@18199 to tolerate lack of the file but no other error 
at an attempt to delete it.
The same applied to the index file deletion.

The cset carries pieces of manual merging.
