[RESEND PATCH] misc: bcm-vk: Specify the minimum number of IRQ vecs

[Breno Leitao]

During bcm_vk_probe(), pci_alloc_irq_vectors() is called passing the
number of IRQ vectors as 1, but, later, check how many IRQ vectors it
got, and fails if it is smaller than VK_MSIX_IRQ_MIN_REQ.

The most appropriated way to do it is setting the 'min_vecs' param as
VK_MSIX_IRQ_MIN_REQ, instead of one. pci_alloc_irq_vectors() should
know the requirements when called.

The test was done by just loading this module on a machine with a
Valkyrie offload engine hardware.
