NTB: ntb_hw_idt: replace IS_ERR_OR_NULL with regular NULL checks
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.
Fixes: bf2a952d31d2 ("NTB: Add IDT 89HPESxNTx PCIe-switches support")
