NTB: ntb_hw_idt: replace IS_ERR_OR_NULL with regular NULL checks
[ Upstream commit 1b7619828d0c341612f58683e73f279c37e70bbc ] Both devm_kcalloc() and devm_kzalloc() return NULL on error. They never return error pointers. The use of IS_ERR_OR_NULL is currently applied to the wrong context. Fix this by replacing IS_ERR_OR_NULL with regular NULL checks.
