libiberty: Fix memory leak in ada_demangle when symbol cannot be demangled.
When a symbol cannot be demangled in ada_demangle a new demangled VEC
will be allocated without deleting the demangled VEC already in use.
Running testsuite/test-demangle under valgrind will show the leak for
this entry in testsuite/demangle-expected:
# Elaborated flag (not demangled)
--format=gnat
x_E
<x_E>
11 bytes in 1 blocks are definitely lost in loss record 1 of 1
at 0x4C27BE3: malloc (vg_replace_malloc.c:299)

by 0x402C59: cplus_demangle (cplus-dem.c:892)
by 0x400FEC: main (test-demangle.c:317)
libiberty/ChangeLog:
* cplus-dem.c (ada_demangle): Initialize demangled to NULL and
XDELETEVEC demangled when unknown.
