perf annotate: Fix memcpy size in arch__grow_instructions()
The memcpy() in arch__grow_instructions() is copying the wrong number of
bytes when growing from a non-allocated table.
It should copy arch->nr_instructions * sizeof(struct ins) bytes, not
just arch->nr_instructions bytes.
This bug causes data corruption as only a partial copy of the
instruction table is made, leading to garbage data in most entries and
potential crashes
Fixes: 2a1ff812c40be982 ("perf annotate: Introduce alternative method of keeping instructions table")
