[PATCH -next] crypto: inside-secure - Fix build error without CONFIG_PCI

[YueHaibing]

If CONFIG_PCI is not set, building fails:

rivers/crypto/inside-secure/safexcel.c: In function safexcel_request_ring_irq:
drivers/crypto/inside-secure/safexcel.c:944:9: error: implicit declaration of 
function pci_irq_vector;
 did you mean rcu_irq_enter? [-Werror=implicit-function-declaration]
   irq = pci_irq_vector(pci_pdev, irqid);
         ^~~~~~~~~~~~~~

Use #ifdef block to guard this.

Fixes: 625f269a5a7a ("crypto: inside-secure - add support for PCI based FPGA 
development board")
