[gdb/symtab] Fix htab_find_slot call in read_call_site_scope
In read_call_site_scope we have:
...
call_site_local.pc = pc;
slot = htab_find_slot (cu->call_site_htab, &call_site_local, INSERT);
...
The call passes a call_site pointer as element. OTOH, the hashtab is created
using hash_f == core_addr_hash and eq_f == core_addr_eq, so the element
will be accessed through a CORE_ADDR pointer.
This is not wrong (at least in C), given that pc is the first field in
call_site.
Nevertheless, as in call_site_for_pc, make the htab_find_slot call match the
used hash_f and eq_f by using &pc instead:
...
slot = htab_find_slot (cu->call_site_htab, &pc, INSERT);
...
Tested on x86_64-linux.
