octeontx2-pf: fix NULL deref of af_xdp_zc_qidx on rep setup
In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: fix NULL deref of af_xdp_zc_qidx on rep setup af_xdp_zc_qidx tracks receive queues using AF_XDP zero-copy and is allocated during PF/VF probe. Representors and other non-AF_XDP paths leave the pointer NULL, but several call sites used test_bit() on it unconditionally. Switching to devlink eswitch mode creates representors and runs otx2_init_hw_resources(), which reaches otx2_pool_aq_init() and oopses when dereferencing the NULL bitmap. Add NULL checks before every af_xdp_zc_qidx test_bit() use in the RSS, ethtool, XSK, and pool init paths.
