qed: Fix a potential use-after-free in qed_cxt_tables_alloc
[ Upstream commit b65d52ac9c085c0c52dee012a210d4e2f352611b ]
qed_ilt_shadow_alloc() will call qed_ilt_shadow_free() to
free p_hwfn->p_cxt_mngr->ilt_shadow on error. However,
qed_cxt_tables_alloc() accesses the freed pointer on failure
of qed_ilt_shadow_alloc() through calling qed_cxt_mngr_free(),
which may lead to use-after-free. Fix this issue by setting
p_mngr->ilt_shadow to NULL in qed_ilt_shadow_free().
Fixes: fe56b9e6a8d9 ("qed: Add module with basic common support")
