gdb: restore nullptr check in compunit_symtab::find_call_site
Commit de2b4ab50de ("Convert dwarf2_cu::call_site_htab to new hash
table") removed this nullptr check for no good reason. This causes a
crash if `m_call_site_htab` is not set, as shown in PR 32410. My guess
is that when doing this change, I tried to make `m_call_site_htab` not a
pointer, removed this check, then realized it wasn't so obvious, and
forgot to re-add the check.
