Subject: [PATCH 3/3] infiniband: pvrdma: constify pci_device_id.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  10774	   1872	      8	  12654	   316e infiniband/hw/vmw_pvrdma/pvrdma_main.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  10838	   1808	      8	  12654	   316e infiniband/hw/vmw_pvrdma/pvrdma_main.o
