media: ngene: avoid unused variable warning 

The newly added pdev variable is only used in an #ifdef, causing a
build warning without CONFIG_PCI_MSI, unless we move the declaration
inside the same #ifdef:

drivers/media/pci/ngene/ngene-core.c: In function 'ngene_start':
drivers/media/pci/ngene/ngene-core.c:1328:17: error: unused variable 'pdev' [-Werror=unused-variable]

Fixes: 6795bf6264 ("media: ngene: convert kernellog printing from printk() to dev_*() macros")
