Avoid a use-after-free deleting 8-bit keys from stashes
This code path only affects symbol tables, and can't be reached by regular
Perl code. It is only reachable using the XS API to delete a key from a
stash where the key was in the 8-bit range but passed in UTF-8 encoded.
This has been in the code since it was added in Oct 2010 by commit
35759254f69c7bfa:
Rename stashes when they move around
Also there is no need to call SvPV() on keysv in S_hv_delete_common() as
its caller has always already done this. This entire code is not KISS.
